▲ On the advertisement board of a real estate in Lichuan, the value of Chongqing PM2.5 was enlarged and matched with a picture of a gas mask, deliberately creating a tense atmosphere.

　　Chongqing Evening News "Chongqing PM2.5 250, Lichuan has 362 days of excellent air quality throughout the year … …” This is what a real estate in Lichuan City, Hubei Province said on the promotional advertisement list distributed in some districts of the main city yesterday, which caused great resentment among the citizens. Some citizens angrily told the Chongqing Evening News reporter that the advertisement seriously vilified the image of Chongqing. "Even people who repair houses are of such quality. The quality of the repaired houses can be imagined. Who dares to buy such a house that is advertised indiscriminately?"

　　Yesterday at noon, a netizen whose real name was @ Zheng Jian, director of Bayu Public Welfare Development Center in Yuzhong District, Chongqing, posted a photo of an advertisement for a real estate in Lichuan on Weibo. The words "Chongqing falls, Lichuan sticks to it" in the center of the page are very eye-catching. Under the eight words, "Chongqing PM2.5 250, the average summer temperature in Lichuan is 22℃, and the number of days with excellent air quality in Lichuan is 362 days". Among them, the fonts of "Chongqing" and "250" are obviously enlarged, and they are changed to more eye-catching red.

　　Zheng Jian wrote at the top of the picture, "The sales advertisement made by a real estate in Lichuan, Hubei Province is too derogatory to Chongqing. Can such an advertisement actually pass the examination? First of all, the PM2.5 in Chongqing exceeded 250 in 2015 for a few days; From April to October, the number of days of pollution is generally less than one month, and most of the time the primary pollutant is ozone. However, the advertisement of the real estate actually said that Chongqing PM2.5 reached 250, which is simply alarmist and slanders the image of Chongqing. "

　　As soon as Weibo was issued, it spread widely on social networks, which attracted a lot of public discussion. Liao Xiaojia, who lives in Jiaheyuan Community near the Auditorium in Yuzhong District, was very angry after seeing the advertisement, because she felt that the air quality in Chongqing had been good in recent years. The reason why this advertisement plays the air quality card is probably that the local real estate market played more cool cards in previous years. However, the competition among peers is fierce, and now we can’t find new gimmicks. Let’s take air quality as an example. Liu Dan, a citizen who works in jiangbei mouth, is quite disgusted with the number "250" in the advertisement, thinking that this number is too fake and uncomfortable. Some citizens have made it clear that who dares to buy this kind of property with unlimited publicity?

　　Yesterday afternoon, Chongqing Evening News reporter contacted Zheng Jian. Speaking of this promotional advertisement, Zheng Jian is still very indignant. "I received this advertisement in a community in the North Ring Road this morning, and it was marked ‘ 250’ This figure is used as a gimmick. Is it bullying Chongqing that no one can understand? How dare such a property come to Chongqing to sell a house? Everyone in Chongqing should resolutely resist it. " Zheng Jian said.

　　Chongqing Evening News reporter learned from Jiangbei District Environmental Protection Bureau yesterday that around noon yesterday, the District Environmental Protection Bureau received a complaint about the advertisement. The district environmental monitoring detachment, together with the law enforcement officers of Guanyinqiao business circle, immediately rushed to the agency of the company in Langqing Square in the business circle at about 5 pm.

　　"The law enforcement officers of the environmental monitoring detachment told them that this kind of advertising language conveys the wrong information, which seriously misleads the public and may even cause panic." The relevant person in charge of the Jiangbei District Environmental Protection Bureau told the Chongqing Evening News reporter that while criticizing and educating the relevant personnel of the agency, the law enforcement officers of the business district collected misleading publicity materials on the spot and asked the agency to rectify immediately.

　　Chongqing Evening News reporter Wan Li Tao Kun He Huaixiang photo report

　　Industrial and commercial developers have no right to publish air quality.

　　Is this promotional advertisement, which has aroused strong public dissatisfaction, appropriate in content release? Chongqing Evening News reporter interviewed the industrial and commercial department yesterday.

　　The relevant person in charge of the Advertising Department of Yuzhong District Administration for Industry and Commerce said that there are at least three things wrong with this advertisement: First, the developer itself is not qualified to release air quality information, and such information can only be released by a few designated institutions and departments such as environmental protection; Secondly, PM2.5 is a dynamic value, which may be different every day or even every hour. It is obviously inappropriate for the advertisement to replace the dynamic value with a fixed value. Third, the advertising content is suspected of misleading consumers. Once consumers find that the actual situation is different from the advertising, the developer will violate the contract law. Moreover, its wording really makes people feel that it is slandering Chongqing.

　　Environmental protection Chongqing air quality ranks in the middle and upper reaches.

　　"This company is completely misleading the public by publishing the wrong air quality information at random." Yesterday afternoon, after seeing this exaggerated advertisement, the relevant person in charge of the Atmospheric Department of the Municipal Environmental Protection Bureau expressed anger. He said that the data on air pollution should be based on the authoritative data released by the environmental protection department, and citizens should not trust these information of unknown origin.

　　The person in charge said that the Law on the Prevention and Control of Air Pollution, which came into effect on January 1 this year, stipulates that no unit or individual may release the forecast and early warning information of heavy pollution weather to the society without authorization. If such information is released without authorization, it will be punished by the public security organs according to law. Therefore, it may be illegal to publish information about heavy air pollution at random.

　　"In recent years, the overall air quality in Chongqing has continued to improve." The person in charge said that in recent years, the city has made great efforts to control air pollution and improve air quality, and has achieved certain results. In 2013, the average annual concentration of PM2.5 in the main city was 70 μ g/m3, which dropped to 57 μ g/m3 last year. Last year, the number of days with excellent air quality in the main city reached 292 days.

　　"At present, Chongqing’s air quality is at the middle and upper reaches of the country and is in the forefront in the west." The person in charge said that if ranked by the number of days with excellent air quality, Chongqing ranked 10 th among 31 municipalities and provincial capitals in 2015; If ranked by PM2.5 concentration, Chongqing ranks 15th among 31 municipalities and provincial capitals.

　　The person in charge also told the Chongqing Evening News reporter that last month, the municipal government issued the "Decomposition of Key Tasks for Air Pollution Prevention and Control in 2016", requiring that the number of days with excellent air quality in our city should reach 300 this year, and the number of days with heavy air pollution should also be controlled at a lower level.

　　The agency apologized to the public.

　　This property that aroused public indignation, was this advertisement launched to stimulate sales for bloggers’ eyes, or was it unintentional? With all kinds of questions, the Chongqing Evening News reporter came to the Chongqing agency of the property near Langqing Square in Guanyin Bridge at 4 pm yesterday.

　　However, in the store, the Chongqing Evening News reporter did not find this controversial advertisement list, and the publicity materials placed at the front desk were also very common. The staff said that after receiving a large number of complaints from the public, they had taken these advertisements off the shelves in the afternoon.

　　The relevant person in charge of the real estate sales department in Lichuan, Hubei Province also said when communicating with the Chongqing Evening News reporter that they are still unclear about this matter. The specific marketing is the responsibility of the Chongqing agency, but they will immediately rectify it.

　　Subsequently, the Chongqing Evening News reporter contacted the manager of the Chongqing agency of the property. Manager Xiong introduced that 10,000 copies of these advertisements were printed and distributed on the morning of the 2nd, and 2,000 copies were distributed as of that afternoon. As for the fact that the words on the advertisement sheet caused public indignation, the agency did not consider it comprehensively, and apologized to the people of Chongqing for this. The remaining 8,000 advertising leaflets will be recycled and will not be distributed, and the advertising leaflets will be revised again.

　　There is no limit to advertising creativity and promotion.

　　In fact, this is not the first time that someone has played the edge ball and used the name of Chongqing to attract attention to promote sales. Four years ago, there was a slogan "I rely on Chongqing" from other places to promote myself, and the result was quickly stopped by the industrial and commercial department. This time, foreign real estate projects are suspected of "washing" Chongqing. The key is that the purpose of "washing" is to want Chongqing people to pay for consumption. Of course, Chongqing people will not agree to such a thing.

　　Since the advent of the Internet, all kinds of unlimited promotions have emerged one after another. Under the guidance of the concept of eyeball economy, as long as it can attract click-through rate, even out-of-place marketing is applauded, because as long as the click-through rate is high, advertisements can be cheated. Nowadays, this endless streaking promotion is spreading to the offline.

　　It is understandable to be creative in advertising, but it must not be shocking to the infinite. Because advertising also has a strong guiding role, it not only conveys business information, but also exerts a subtle influence on people’s values, moral norms, social norms, lifestyles and so on. Therefore, in response to this chaos, the relevant departments must strengthen supervision over the advertising content and publishing platform, and must not take it lightly and never let it drift.

　　The surge of spring tide urges people to advance, and sails with the east wind. On April 8th, the Yancheng High-quality Development Project Observation Promotion Meeting was held in Dafeng District. The participants’ footprints spanned the main battlefield of the Yangtze River Delta Integrated Industrial Development Base and concentrated on "reviewing" the latest achievements of high-quality project construction in Dafeng District.

　　From Dafeng Economic Development Zone, an important part of "the core of intellectual creation", to a high-tech zone that shines with intelligence and is "in full bloom", and then to a port that thrives on the sea and develops green. Everywhere we go, we are full of vitality, and a picture of green transformation comes into view. The industrial clusters with distinctive characteristics have risen strongly, which has become a vivid footnote for Dafeng to "be the vanguard of the integrated development of the Yangtze River Delta", which makes people touch and feel the strong pulse and surging trend of high-quality development in Dafeng District.

　　Grasping projects means grasping development, and seeking projects means seeking the future. In recent years, Dafeng District has firmly grasped the core of industry and unswervingly promoted chain development. The annual invoicing sales of three strategic emerging industries, new energy and equipment manufacturing, new energy auto parts and new generation electronic information, exceeded 40 billion yuan. Honeycomb energy lithium-ion power battery and Bomin electronic high-density interconnection printed circuit board are listed as major projects in this year’s province.

　　Yancheng Bomin High Density Interconnected Printed Circuit Board Project

　　Jiangsu Bomin Electronics Co., Ltd., as the head enterprise of electronic information industry in Dafeng District, has aimed at the forefront of the industry in recent years, accelerated the "change from intelligence to digital" and continuously enhanced the innovation momentum, and built the first provincial-level intelligent manufacturing demonstration factory in Dafeng District.

　　Walking into the high-density interconnection PCB project workshop of this enterprise, sophisticated equipment and testing facilities such as cutting-edge press, vacuum etching line, fully automatic LDI exposure machine and fully automatic optical circuit inspection are dazzling, and the charm of "smart factory" is self-evident. At present, the project is in trial production. When it is fully completed and put into production, it is estimated that the annual invoice sales will be 3 billion yuan and the tax revenue will be 200 million yuan.

　　"Our high-end products can replace imports. Among them, Anylayer HDI boards focus on 5G new markets, big data, artificial intelligence, industrial Internet and other fields. IC carrier boards and Micro LED fill the gaps in domestic products, which will drive the downstream enterprises of integrated circuits to develop together and break the monopoly of foreign enterprises." Sheng Li, the general manager of the company, called several treasures.

　　Jiangsu jinweier machinery co., ltd　

　　The manufacture of high-end products is inseparable from high-end technology and production equipment. As a customized intelligent equipment manufacturing head enterprise, Jiangsu Jinwei Machinery Co., Ltd. persists in technological innovation and continuously increases independent research and development investment. Through cooperation with universities such as Tsinghua and Southeast University, it has successfully developed more than 60 kinds of extrusion equipment for plates, sheets and films required in various application fields. In the workshop of the enterprise’s high-end intelligent equipment manufacturing project, a series of EVA photovoltaic cell packaging hot melt adhesive film production lines attracted the attention of the participants.

　　"EVA packaging film is mainly used for packaging crystalline silicon and some thin-film solar cell modules. Because of its advantages in adhesion, durability and optical characteristics, EVA packaging film is more and more widely used in current modules and various optical products." The person in charge of the enterprise said that the company’s EVA photovoltaic film production line technology is internationally leading, and the current global market share is as high as 70%-80%.

　　Yancheng honeycomb energy lithium-ion power battery

　　The honeycomb energy power battery project with a total investment of 10 billion yuan is one of the first major projects in the province this year, and it is also the first major project to land in Yancheng Yangtze River Delta integrated industrial development base. "High level of intelligent manufacturing, strong ability of independent innovation and wide market application" is the general evaluation given by the participants after observing the enterprise.

　　It is understood that Honeycomb Energy has achieved mass production of cobalt-free batteries with a series of subversive innovative technologies such as high-speed lamination and cobalt-free batteries, and has become more than 30 high-end customers such as Great Wall Motor strategic suppliers. At present, the project has entered the trial production stage. After it is completed and put into production, it will realize the annual sales of 12 billion yuan and tax revenue of 500 million yuan, and become an important core industrial base of blade batteries in the Yangtze River Delta region.

　　Hongshun silicon-based semiconductor technology co., ltd

　　"The production technology of high-purity quartz sand with high temperature resistance of 1800℃, 99.998% and above has long been monopolized by foreign enterprises such as the United States and Norway, and the production process is extremely complicated. At present, we have this completely independent intellectual property right and hold the corresponding patent, which has solved the problem of silicon rod production ‘ Get stuck in the neck ’ Difficult problem. " Listening to the introduction of the person in charge of Hongshun Silicon-based Semiconductor Technology Co., Ltd., the participants couldn’t help but praise it.

　　It is understood that the Hongshun silicon-based semiconductor material project is not only internationally advanced in process technology, but also extremely high in adsorption value. Through this enterprise, it has continuously built a strong chain to supplement the chain and attract more well-known silicon materials enterprises at home and abroad to invest in Fengfeng. In the near future, an influential domestic silicon material industry production base will rise from here.

　　Trina Solar 10GW Photovoltaic Module Project

　　It took only 120 days from breaking ground in March last year to mass production at the end of June. Trina Solar’s 10GW photovoltaic module project set a new speed in the industry, which was started, completed and mass produced that year. Stepping into Trina Solar’s spotless project workshop, with 20 automatic production lines running at full capacity, 210 ultra-high power components with the most advanced technology in the industry quickly rolled off the assembly line.

　　Wu Jianfeng, the person in charge of Trina Solar Yancheng, used four key words: "construction speed benchmark, process technology benchmark, cost control benchmark and intelligent management benchmark" to intensively express the industry leading and super competitiveness of the project to the participants. It is understood that the whole process of the project is automatic and intelligent, and AI technology is introduced into inspection and testing to improve the abnormal detection rate and reduce the intensity of work; The actual output of a single line exceeds 500MW/ line, and the average output value per mu exceeds 30 million yuan, ranking first in the industry. It can realize annual invoicing sales of 13.7 billion yuan and tax revenue of 250 million yuan.

　　Yueda Automobile (Dafeng) Kechuangyuan

　　Yueda Automobile (Dafeng) Science and Technology Park is an important supporting project of Yancheng automobile industry chain, covering an area of 122 mu, with a total investment of about 500 million yuan. Focusing on the functional orientation of "scientific and technological innovation, industrial incubation and scientific and technological service", it is committed to building a comprehensive scientific and technological innovation park of automobile industry, which integrates R&D design, testing, project incubation and demonstration application.

　　At present, it has settled in 4 intelligent networked enterprises, 2 new energy automobile enterprises, 6 testing and testing companies and 3 service organizations. After visiting the Smart Car Innovation Center, Science and Technology Incubation Center, Intelligent Networked Test Site, Yangtze River Delta (Yancheng) Intelligent Networked Automobile Testing Technology Innovation Alliance and other sites, the participants highly appreciated the project’s practice of relying on the unique geographical and industrial foundation of the port area, giving full play to the unique advantages and industry resources of the China Automobile Test Site, making every effort to build an intelligent networked demonstration highland and building the ecology of the whole automobile industry chain.

　　Rural revitalization is the "ballast stone" to achieve high-quality development.

　　Demonstration Project of Rural Revitalization in Xinzhong Village, Xituan Town

　　The demonstration project of rural revitalization in Xinzhong Village of Xituan Town is a vivid epitome of the comprehensive implementation of rural revitalization demonstration towns and villages in Dafeng District. As the first batch of rural revitalization demonstration villages in the whole region, Xinzhongcun adheres to the mode of "small incision, replicability and mass participation", focusing on the comprehensive improvement of the rural environment with all elements of "Tianshui Road Forest Village", promoting the rebirth of old houses with small investment, creating a new look with small courtyards, and retaining homesickness memories with small nodes.

　　When driving into Xinzhong Village Farm Belt, the villagers spontaneously donated old bricks, tiles, window frames and other old objects, and created node sketches through combination decoration, presenting exquisite art at a small cost, telling the past years and awakening homesickness memories. The Green Field Xinzhong Agricultural Park is full of vitality, with smart greenhouses, new farmers’ homes, fat horse shops, picking gardens, Xinzhong Station and other formats, and it is open to welcome guests.

　　This is not only a beautiful countryside, but also a grass-roots park. The "1+18" business entities gather here, attracting social capital investment of 200 million yuan, and building a benefit linkage mechanism of "government building, farmers singing opera and farmers increasing income". The fruits and vegetables in the park are sold to the Yangtze River Delta region for more than 200 million yuan every year. Participants walked, watched and discussed all the way, and spoke highly of the project’s efforts to build a rural complex with village and garden characteristics, with social capital investment as the main force, high-standard farmland construction as the starting point and the upgrading of old villages as the focus. They thought that this "new-middle experience" with small investment, replicability and popularization was worth learning.

　　The Yellow Sea coast is in spring tide, and the project construction is competing in Qian Fan. Dafeng District will focus on the integration of salt abundance, provinces and the Yangtze River Delta, highlight the two key words of "integration" and "high quality", give full play to the strength of the whole region, collect the wisdom of the whole region, and promote the integrated industrial development base of the Yangtze River Delta to "show its image in one year, make great changes in three years, and achieve results in five years", and strive to turn its characteristic advantages into high-quality development momentum, and sing the "Dafeng Song" of being the pioneer of high-quality development in coastal areas.

Local employees at work

　　Cctv news After six years’ struggle, the construction of Sinclair Hydropower Station in 2016 has entered a fruitful harvest season.

　　At the celebration ceremony of the first batch of units put into operation, Vice President Grasse of the Ecuadorian government said that the cooperation between the Chinese and Ecuadorian people can achieve great things.

　　China’s ambassador to Ecuador, Wang Yulin, said that Sinclair Power Station has played an exemplary role and written a new chapter in China-Ecuador cooperation.

　　Yes, with sincere cooperation between China and Ecuador, the virgin forests that have been sleeping for thousands of years along the Amazon River and the Andes that have been silent for thousands of years have been awakened, and majestic dams, wide factories and towering iron towers stand tall. The singing of hydraulic turbines replaced the noise of the river, and all the silver wires delivered powerful electricity to the Ecuadorian people … …

　　While benefiting the local people and realizing the dream of one-third of the local population to use electricity, China Power Construction has also built its own dream of "going out" and creating a new pattern of international operation, which has played an exemplary role and written a new chapter in Sino-Ecuadorian cooperation.

　　A piece of white paper is easy to write.

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 Master China and Ecuadorian apprentice

　　On July 28th, 2010, Sinclair Hydropower Station (hereinafter referred to as CCS) started construction. Under the leadership of several project leaders over 35 years old, a group of "dolls" under the age of 27 and 28 started the construction of China’s largest hydropower station overseas at that time and China Power Construction Company’s first project to enter the middle and high-end market in South America. This is a "zero international" experience project execution team without any international construction experience. As the saying goes, "a piece of white paper is easy to write".

　　Hong Kun, director of CCS project and then secretary of the Party Committee of the 14th Bureau, said: "It was really a mixture of excitement and pressure, excitement and anxiety."

　　The "first word" written by the young team is a Project Management System Document covering the whole process from design to construction, production to management, front line to logistics, based on a comprehensive investigation and evaluation of local politics, law, taxation, labor, equipment, materials and logistics, so as to strengthen the scientific, systematic and risk controllability of project management and control.

　　They set up a biweekly "high-level meeting" composed of the Chinese side, the owner and the consultant, which strengthened the consultation and communication ability of the three high-level parties. Although there was a 12-hour meeting, disputes and debates continued, but a consensus was reached and major issues affecting the smooth implementation of the project were solved in time.

　　They also set up the Joint Dispute Committee (CDB), chaired by Bernan, a famous Spanish lawyer, with Karl, a German engineer, and Albordt, a Colombian engineer as members, as a neutral third party to intervene in the implementation of CCS project, so as to avoid time-consuming and costly international arbitration and litigation, solve disputes fairly and reasonably, and better balance the interests of the parties to the contract. This meeting has been held nine times so far, and 13 disputes have been successfully resolved, with a claim amount of hundreds of millions of dollars and a construction period of 24 days.

　　The c of EPC general contract refers to the project construction. The main construction of ccs project mainly includes four parts: the first hub, the water conveyance tunnel, the regulating reservoir and the underground powerhouse. The implementation period is long, the span is large, and there are many difficulties. "Cost control is particularly important." Zhang Degao, the chief economist of the project, said: "We systematically analyze and calculate the total cost of the project once a year, and six versions have been formed so far."

　　Analyze and calculate the total cost of the project on a regular rolling basis, deeply analyze the composition and changes of various expenses, and find out the changes and causes of the expected profits, so as to study and formulate targeted control measures, which can control the project cost as a whole, reduce contract risks, continuously improve the management level of overseas projects and ensure the overall operating results of the project.

　　In their view, "progress is the biggest cost". Wang Fengjun, the business assistant, said: "We often go deep into four construction departments, and work with the construction manager to carefully analyze the cost input of people, materials and machines, determine the key links and key processes that affect the cost, rectify the deviation in time, and check on a monthly basis to ensure the smooth completion of major node goals."　

　　During the difficult excavation of a water conveyance tunnel with a total length of 24.8 kilometers and a maximum excavation diameter of 9.15 meters, they conducted 11-stage tool consumption and 14-stage over-footage assessment on the construction of TBM1, which effectively promoted the TBM1 to achieve a good result of an average monthly footage of 663 meters and a maximum monthly footage of 1,059 meters. The incentive assessment of TBM1 segment production was quantified to each segment and each ring, which also achieved good results. The production task of TBM1 segment was successfully completed ahead of schedule on February 22, 2014.

　　In the ccs project department, there is a story that a management department directly organizes and directs the construction. In February 2012, the power station construction was in full swing, and a large number of construction and management personnel entered the site. However, the construction of the living camp was seriously delayed due to the slow construction of local subcontractors, especially the No.2 main site as the project office and production command center. As a result, the owner has serious doubts about the construction management ability of the project department.

　　In order to reverse the passive situation, the project was always ordered by Zhang Degao to be the production commander of the construction of Camp No.2 during the day and handle the complicated affairs of contract business at night. To build a good camp according to the high standards of first-class large multinational companies, the time was tight and the task was heavy. He led a deputy director of the business department to decompose and refine the construction schedule of the camp, and reversed the construction period, so that the construction task of Camp 2 was completed on schedule in a swamp. Although Zhang Degao’s face has become a "belt face" — — When the safety helmet is taken off, a circle of white hat belt marks are conspicuously left on the tanned face, but the good construction organization and management ability have completely changed the previous bad impression of the owner.

　　Facing the uniform, beautiful environment and supporting facilities of Camp 2, the owner’s general manager praised: "I like every grass and tree in the camp".

　　You shouldn’t be a sinner if you are bitter and tired

Zhou Xiancai and his fiancee Lorena

　　In the interview with ccs project department, I also heard a new thing. The project department set up a design and research institute. Including more than 20 external local engineers, the number of design and research institutes reached more than 100 at the peak, and the current director is He Guoxiong, 28.

　　The e of EPC general contracting refers to engineering design. The design of CCS project is mainly divided into conceptual design, basic design and detailed design, and the design documents of each stage need to be strictly approved by the owner. The design scope includes the main works such as the head hub, water conveyance tunnel, water storage reservoir, water diversion and power generation system, and ancillary works such as permanent operation village, power transmission and transformation lines and aerial ropeway. If the main workload is calculated by the number of drawings, calculations and reports in the detailed design stage, the total amount is about 9000.

　　Design work is the leader of the whole project construction, which plays a vital leading role in the progress, quality and success of the project construction. The design management burden of coordinating all parties involved in the design of CCS power station, introducing and controlling well-known design and consulting institutions at home and abroad is on the shoulders of young He Guoxiong.　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　
　　"Language barrier is the biggest difficulty," He Guoxiong said. "The contract language is Spanish, and we are very short of Spanish translation familiar with hydropower projects, which makes it a great challenge to prepare western design documents. Every time we complete a document, we have to go through Chinese — — English — — In the conversion process of western languages, the owner’s letters have to go through the same conversion. "

　　Faced with language difficulties, standardization difficulties and conceptual differences, the design institute adopted a new design management model, introduced "outside brain" and local engineers to promote "design after design", and completed the review and approval of the project conceptual design in only one year; It took 13 months to complete 12 volumes of basic design reports, and completed about 12,080 design criteria, calculations, reports and drawings in the detailed design stage, with the highest monthly completion rate of 500 and the highest monthly approval rate of 400. By the end of 2015, all the designs of the main project have been completed.

　　P of EPC general contracting refers to the procurement of engineering equipment. The procurement chain of permanent mechanical and electrical equipment for CCS project is long, from mechanical and electrical conceptual design, procurement bidding, factory supervision and factory acceptance, to land and sea transportation, on-site acceptance, installation inspection, commissioning and operation, and so on. Many equipment and materials are gathered in the construction site from famous manufacturers in China and the world, and they have to go through 11 major procurement processes and 6 major installation processes, and there are countless small round-trip processes.

　　On April 11th, 2013, Feng Yanguo, the representative of China Power Construction International Company and the electromechanical manager of the project department, came to Paris to accept the 500 kV high-voltage cable. Hardly had he got off the plane when he received the news of his mother’s death. After a week of acceptance with tears in his eyes, he came home, holding his mother’s urn, unable to cry … …

　　When transporting an auxiliary transformer with a length of 4.1 meters, a width of 3.2 meters and a height of 5.6 meters, I met a bridge opening with a height of less than 5 meters on the way, and the equipment could not pass. Liu Helin, an electromechanical assistant, and Zhao Lei, a young man who just left the school in 2011, ran before and after a while in a rainstorm and a while in the sun, but they just came up with a strange trick of "changing big tires for small tires", which reduced the height of the truck and successfully passed through bridge opening. Every day, I start at six o’clock in the morning and stop at five o’clock in the afternoon. Sometimes I drive only 30 kilometers in one day. From the port city of Guayaquil to the construction site, they ate and lived with local drivers and followed the car for eleven days, with a journey of 710 kilometers.

　　According to statistics, there are 188 procurement contracts for permanent mechanical and electrical equipment and materials of CCS project, including 54 main contracts, 96 supplementary contracts and 23 contracts in the form of construction materials. The main signatories are 33 Chinese-funded enterprises, 5 Sino-foreign joint ventures and 3 foreign-funded enterprises in Japan, France and Norway, with a purchase contract value of more than 540 million US dollars.

　　"If there is a problem with the permanent mechanical and electrical equipment and it can’t send electricity, then all the efforts made by thousands of people for the construction of power stations will be wasted. We would rather be bitter and tired than be sinners, "Liu Helin said.

　　Thanks to China Hydropower.

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 Bibiana and Dr. China who rescued her

　　Bibiana, 25, was a waitress in a small restaurant in St. Louis village near Camp 2 of CCS Power Station. On the evening of May 29th, 2012, she suddenly had a stomachache and wanted to have a baby. After receiving the news of asking for help, CCS Project Department immediately dispatched a doctor, nurse and an ambulance from Camp 2, and sent her to Chaco City Hospital more than 30 kilometers away in time to ensure the safety of mother and child. When mentioning this matter, Bibiana always said excitedly: "Thanks to the selfless help of China Hydropower!" Today, she and her sister are both secretaries in the project administration department, and her brother-in-law is a driver.

　　There are many bends and steep slopes along the CCS site, where there is no rain every day, frequent landslides and rollover accidents. One day at 6 o’clock in the afternoon, Ma Guihong, manager of the plant construction department, received a phone call from Wang Jinlong, a safety assistant: "A local bus from Lago to Quito had a rollover accident near the volcanic town, and two passengers were still under it. Please send a 16-ton crane to participate in the rescue immediately! "

　　The accident site is 33 kilometers away from the construction department of the factory building. The highway grade is low, the dark road is narrow and curved, the crane tonnage is heavy and the body is long, but time is life. The construction department can’t take care of these things, so it immediately sends a crane, a pickup truck and six employees to the scene … … When the rescuers sent the wounded to the ambulance and returned to the station, it was already more than 12 o’clock in the middle of the night.

　　According to the data, in 2015 alone, the hospital of CCS Project Department provided 33,867 person-times of diagnosis and treatment services for local people, carried out 12 social emergency medical rescues, and treated and referred 39 injured people.

　　Give a rose, but leave a fragrance in your hand. In recent years, CCS Project Department has invested more than 500,000 US dollars to help local people and give back to local society. They actively improved roads, repaired gardens, installed drinking water pipes, built school guardrails and presented school supplies for Chaco City, where the project is located, and established the hydropower image of China with a good reputation. The project general manager Zi Jiquan won the title of "Honorary Citizen of Chaco City" for many times.

　　At the construction site, we also interviewed Zhou Xiancai, an interpreter from the construction department of Shangpingdong. Xiao Zhou, a 28-year-old graduate of Xi ‘an International Studies University, has been in constant contact with the local secretary Lorena employed by the office for more than three years, and has developed a feeling of admiration. Lorena said in blunt Chinese: "China young man, hard-working, handsome!" Earlier this year, Lorena followed Xiao Zhou back to her hometown in Ankang, Shaanxi Province for the Spring Festival, and visited Xi ‘an and Chengdu. She is very appreciative of the sense of responsibility of China’s young man and the family’s reunion, and she is very interested in China’s bell tower, Wild Goose Pagoda, Wu Hou Bar and other ancient buildings. She said: "In the future, I will follow wherever I am thoughtful."

　　China element and China hydropower have changed the local social outlook and people’s life, and had a great impact on the development of Ecuador.

　　The investment in CCS project is huge, which has brought more than 7,000 direct jobs and 15,000 indirect jobs to the local area. 80% of the employees in the project department are local laborers, including senior managers such as deputy director of technology and manager of human resources department. There are only 10 Chinese employees in the SHSA (Safety, Health, Hygiene and Environment) Management Department, but there are more than 100 local employees.

　　While creating many employment opportunities, the project department has sent high-level skilled technicians to strengthen the training of local employees, and even simple tasks such as binding steel bars are "hands-on". Over the past few years, the project department has held more than 600 multi-level trainings on construction operation, quality and safety and labor management for local employees, with the number of trainees reaching 13,000, and trained more than 1,000 construction team leaders and more than 400 construction technical talents and management talents at all levels, which won high recognition from the local government and people and effectively ensured the smooth progress of the project construction.

　　Embracing the local society with open arms and actively promoting the "localization" of project implementation have become the new normal for China Power Construction to develop overseas business. (Ran Luchao Yu Yong)

The traditional racing bible is being revised, and the international giants’ attention to the event is quietly changing, all because of the big environment.

Self-abandonment of racing giants

There are not many racing giants in the world today. Here are a few that will surely convince the public.

Participated in 1999 and won 13 championships so far. Among them, from the second year of the competition (2000), it won three consecutive championships. In 2004, another five consecutive championships began. In 2010, it was another five consecutive championships.

Has decided to leave the once glorious Le Mans battlefield.

This achievement is quite amazing. By the way, if you mention some details of these ten years, your worship of you may be further deepened. In 2003, EXP Speed 8 won the championship, but it was actually a car in a coat, so strictly speaking, it should have been nine consecutive championships since 2000-this is terrible!

And left, there was only one LMP1 group, I don’t know what it was like.

In addition, R15 TDI Plus, which won the championship in 2010, finished the race with a distance of 5410.713km, creating the longest race distance in the history of the 24-hour Le Mans race, and this record has been maintained to this day.

Now, I have to say goodbye to such a brilliant record, and I have said that I will no longer participate in the Le Mans LMP1 group competition.

This name, it seems, is the same as drawing an equal sign. It is the brand that has won the Le Mans Competition the most times in history, winning the championship for 19 times.

The 917K in 1970 opened the era of Le Mans Competition.

In 2015, he returned to Le Mans and ended the dynasty with 919 Hybrid racing car, and won the championship for three consecutive years. Just after winning this year’s Le Mans championship in June this year, he suddenly announced his withdrawal from the Le Mans competition in LMP1 group.

This year, 919 Hybrid won the championship again in Le Mans Competition, and then suddenly announced the launch of LMP1 group events.

Overnight, he quit one after another, leaving those who had never won the championship alone in the wind.

In recent years, it has dominated the grand prix, making the former giants follow behind them, including Williams, Williams and so on.

Mercedes-has become the ruler today.

However, it is not just announced that it will withdraw, but another influential event in Europe-DTM (German Touring Car Masters). As the most famous touring car race in Germany and even in Europe, DTM represents the highest level of touring car races. In DTM, it is an old-fashioned powerhouse and has been fighting here for more than 20 years.

Quit DTM, stay with two companies, and the future of this event suddenly becomes a mystery.

In 1988, he began to participate in DTM events, won the championship for the first time in 1992, and is now one of the three major DTM teams. After leaving, there will be only two DTM companies, which is also quite unfavorable to the development of DTM. Uncle’s move is not as good as merging into Japan’s Super GT in the future, and the joint venture between the two parties is more exciting.

They all chose formula e.

These three racing giants have left their best fields and where have they gone?

The answer is actually the same: Formula E, FIA electric equation, that is, domain.

A few days ago, when I confirmed my withdrawal from DTM, I confirmed that I would move to Formula E in the future. It is expected that the competition time will start from the 2019/2020 season. In fact, the accumulated experience in the field in recent years will be well used in Formula E events, and focusing on two equations at the same time will not be too complicated for event management.

In fact, I have participated in Formula E race a long time ago, just in the form of cooperation with Abt Schaeffler team. However, it was recently revealed that it will officially enter in the form of an independent team in the 2017/2018 season.

Earlier, it was reported that after leaving Le Mans, it is planned to March in the 2019 season. If so, then the strategic direction will be the same, and the two most important and top-level Formula One competitions on the planet will be launched.

It has also been confirmed that it will participate in the Formula E competition, and the time is 2019/2020 season. This is a decision based on the 2025 strategy. In the future, we will develop civil electric power with Mission E as the blueprint, so as to kick off the model. Obviously, participating in Formula E competition will bring more benefits to the company’s career development.

Why is Formula E so popular?

What else can it be because of? Because of environmental protection.

Germany has announced that it will stop manufacturing and selling internal combustion engines in 2030, which is the most obvious hint for all manufacturers: it’s time to do it well. Not only Germany, but also Denmark, Britain and Sweden have similar policies coming to the fore. Of course, these mainstream European car companies are not so passive, and they are already leading the world in research and development. However, with the promotion of the government and the pace of development, we can go further, such as participating in Formula E.

From the point of view of racing circle, Formula E is getting more and more attention because of environmental protection. Many people you are familiar with have actually participated in this project, such as,,,, and so on. They either set up factories to participate in the competition or provide key technologies.

In a word, Formula E is the most correct event at present, and it will hardly be opposed by any party, because in this era-environmental protection is the greatest.

　　

　　CCTV News:At 1 pm on February 25th, 2017, the Chengdong Police Station of Jingjiang Public Security Bureau in Taizhou City, Jiangsu Province received an alarm from a residential property, and Yangyang, the nine-year-old son of the owner Xiaoye, was missing. Later, Yangyang’s mother received a short message saying that the child had been kidnapped, and asked her to prepare 2 million yuan in cash, which she would pay in hand at Wuxi Railway Station. Jingjiang police quickly organized police to go to Wuxi to cooperate with the local police and investigate around the railway station. At five o’clock the next morning, the police received news that Yangyang’s family found the child’s body under the bed.

　　The police quickly arrived. Through on-site investigation, it was found that the child’s mouth and nose were entangled in tape, and his head and body had been electrocuted, and his hair was covered with blood. After forensic examination and identification, the victim died of mechanical suffocation caused by covering his mouth and nose.

　　Subsequently, the police investigated the video surveillance around the community and found suspicious people wearing hats and masks many times. Yangyang’s father felt that this person was very similar to his colleague Gao, but Yangyang’s mother denied the police’s suspicion, repeatedly saying that Gao had a good relationship with his family. When the child had an accident, he also helped to find it everywhere, and called to comfort himself many times after returning home.

　　Police investigation found that Gao and Yangyang’s mother used to be lovers, and their suspicion of committing crimes further increased. Soon, the police found a payment bill of Gao on a website, and he bought electric batons online. Jingjiang police immediately organized police to arrest Gao.

　　During the trial, Gao reacted calmly, and he denied the killing of Yangyang. After the police showed the gloves with traces of Yangyang and Gao, which were extracted from the flower bed, and a suspicious footprint found under Yangyang’s bed, Gao was finally broken through the psychological defense line and confessed the criminal facts.

　　The suspect Gao, aged 35 (2019), is the head of a department in a large local shipyard. Because of the disagreement between husband and wife, they are addicted to online chat. At the beginning of 2012, he got to know Yangyang’s mother Xiaomei through the Internet, which gradually developed into an extramarital affair. At the end of 2016, Xiaomei came up with the idea of returning to her family and began to neglect Gao. During the Spring Festival of 2017, Gao met several times. As a result, Xiaomei only hurried to take a photo and went home, which made Gao very angry. Gao had the idea of making Xiaomei sad by retaliating against her child Yangyang. Although Gao claimed to like Yangyang, the idea of revenge on Yangyang’s mother Xiaomei made him lose his mind.

　　Defendant Gao said: "I used to watch the mobile phone network video, and I fainted when I saw the electric shock. After a while, I will be fine. Hide the child first, don’t let her find it, and let her be afraid when the child is lost. "

　　In order to ensure the success of the crime, Gao made careful preparation and planning. During January 2017, Gao visited Yangyang’s home several times. At the same time, he also modified the electric batons himself. Fearing that electric shock would cause automatic protection of the circuit, he also sneaked into Yangyang’s house with a stolen key, and reformed the socket line of Yangyang’s house to avoid the safety protection device. At 8 o’clock on February 25, 2017, Gao wore a wig, hat, mask, etc., and then sneaked into Yangyang’s home. After Yangyang took the courier home, he put a knife rest around his neck and pushed Yangyang to the bedroom. Gao used a prepared electric baton to shock the child’s neck, back of the head and other parts many times, but instead of corona Yangyang, it aroused the child’s resistance. Seeing that things were out of control, and worried that Yangyang would identify himself after the incident, the consequences would be unimaginable, so Gao made a malicious move. Gao tied Yangyang’s hands behind his back and wrapped tape around his nose and mouth until he watched the child lose his breath. Later, Gao opened the bed in the bedroom, hid Yangyang under the bed and fled the scene.

　　Although Gao repeatedly said that his behavior was out of control, when he fled the scene, he was unusually calm and carefully wiped the blood and footprints on the scene, and then destroyed some tools for committing crimes. When Xiaomei’s family was looking for Yangyang everywhere, Gao also called and pretended to be kind to appease Xiaomei, trying to find out the news. When he learned that the police were looking for people all over the city, Gao used kidnapping text messages to try to divert the police’s attention and interfere with the police’s investigation.

　　On July 28, 2017, the People’s Procuratorate of Taizhou City, Jiangsu Province filed a public prosecution with the Taizhou Intermediate People’s Court for the defendant Gao’s intentional homicide. Taizhou Intermediate People’s Court formed a collegiate bench according to law and heard the case in public on September 5, 2017. During the trial, the defendant Gao denied the confession in the public security organ and proposed to make a mental appraisal.

　　President Zhou of the criminal court of the court: "The defendant in this case was carefully prepared before the incident. During the incident, he implemented it according to his own plan. After the incident, he pursued advantages and avoided disadvantages, and destroyed and concealed some criminal tools, indicating that the defendant has the ability to recognize and control, and is a normal and rational person. Only when mental illness is possible, the court will allow his application. This case does not meet at least some conditions of mental illness.

　　On November 9, 2017, after trial, Taizhou Intermediate People’s Court sentenced the defendant Gao to intentional homicide, sentenced to death and deprived of political rights for life.

　　Psychological analysis of cases:

　　Psychologist Bi Jinyi: The beginning of this crime started with a middle-aged man having an extramarital affair. This kind of thing is something that only adults can do, so it has nothing to do with childishness. As for being out of touch, I think it’s hard for him to think of this excuse when he talks about being out of touch with the society, because killing people for their lives is the simplest taboo, which is known to all women and children. Killing people for their lives, although our criminal law is not simplified, but the consequences of killing people are unknown.

The latest expert consensus on clinical application of nasal high-flow oxygen therapy for emergency adults, an analysis!

Respiratory doctors should be familiar with nasal high-flow humidified oxygen therapy (HFNC). Since it was applied in mainland China in 2014, HFNC has been rapidly promoted and popularized in recent years, and its clinical effect is obvious to all.

Compared with traditional oxygen therapy (COT), noninvasive positive pressure ventilation (NPPV) and invasive positive pressure ventilation, HFNC has its unique advantages and certain limitations. In February, 2019, the Respiratory Critical Care Medicine Group of the Respiratory Branch of the Chinese Medical Association released the Expert Consensus on the Application of Clinical Norms of High-flow Humidified Oxygen Therapy for Adults (hereinafter referred to as the "Expert Consensus of 2019 Edition"), which gave everyone a comprehensive understanding of HFNC.

With the outbreak of COVID-19 epidemic, HFNC has also played an important role in the treatment of severe and critical COVID-19 patients. Therefore, the Respiratory Therapy Group of the Respiratory Branch of the Chinese Medical Association issued the Expert Consensus on the Use and Management of Nasal High-flux Oxygen Therapy for Patients in novel coronavirus [2] (hereinafter referred to as the Expert Consensus in 2020), which provided guidance for the use of HFNC in patients in COVID-19.

Of course, the clinical application of HFNC is not limited to respiratory patients, and any patient who needs aerobic treatment has potential indications for HFNC. Recently, the Emergency Medicine Branch of the Chinese Medical Association issued the Expert Consensus on Clinical Application of Nasal High-flux Oxygen Therapy for Emergency Adults [3] (hereinafter referred to as the Expert Consensus in 2021), focusing on the application of HFNC in emergency environment.

The guide is so spicy that I can’t read it. Today, the author will summarize and summarize the essence of these three guidelines, and show you what is unique about HFNC and how to use it in patients and emergency environment in COVID-19.

Let’s cut to the chase.

one

Basic concepts and principles of HFNC

In fact, nasal high-flow humidified oxygen therapy (HFNC) is well understood, which is a kind of treatment that can provide patients with high-flow inhaled gas with adjustable and relatively constant oxygen concentration, temperature and humidity through nasal congestion.

Compared with COT, HFNC highlights two advantages: high flow rate and heating and humidification. The common nasal tube has a small diameter, so it is difficult to achieve relatively constant high flow rate and oxygen concentration. However, HFNC can achieve these goals at the same time through high flow rate nasal plug and heating and humidification device.

Figure 1 AIRVO2 HFNC

On this basis, HFNC can also achieve physiological effects similar to NPPV:

Positive End-expiratory Pressure (PEEP) effect: High-velocity gas can maintain a certain level of PEEP, which is beneficial to alveolar recruitment and qi-blood exchange at end-expiratory;

Physiological dead space scouring effect: high-velocity gas can also scour the gas left in the anatomically ineffective cavity of nasal cavity, oral cavity and pharynx at the end of expiration;

Maintain the function of mucociliary clearance system: relatively constant heating and humidifying gas can obviously reduce the dryness of nose, mouth and throat of patients, which is helpful to dilute sputum and expel phlegm;

Reduce the patient’s upper airway resistance and respiratory work: high-flow gas makes the patient not need to inhale hard, which can reduce the inspiratory resistance and reduce the patient’s respiratory work.

Of course, there are still some differences between HFNC and NPPV. The two oxygen therapy methods have their own advantages and are suitable for different patients and oxygen inhalation environments.

Table 1 Differences between HFNC and NPPV

2

Indications and contraindications of HFNC

As the saying goes, although something is good, it depends on whether it is useful or not. When to use it and when not to use it is a topic that everyone really cares about.

In fact, at present, there is no uniform standard for indications and contraindications of clinical application of HFNC. The indications of HFNC recommended by expert consensus in 2019 include:

Patients with mild or moderate hypoxemia (100 mmHg≤ PaO _ 2/fio _ 2 < 300 mmHg), no indication of emergency tracheal intubation and relatively stable vital signs;

Patients with mild ventilation dysfunction (pH≥7.3) can also be used cautiously, but they should be prepared to switch to NPPV or invasive positive pressure ventilation with tracheal intubation.

On this basis, the consensus of experts in the 2020 edition points out that it meets the diagnostic criteria of severe COVID-19 (respiratory distress, respiratory frequency ≥30 beats/min; At rest, oxygen saturation is ≤ 93%; Patients with PaO2/FiO2≤300mmHg) can consider using HFNC.

The 2021 edition of expert consensus did not specifically list the indications of HFNC, but recommended specific clinical scenarios:

Acute type I respiratory failure: using HFNC instead of COT to reduce the rate of tracheal intubation and the need for respiratory support upgrade; Patients who have received NPPV can try HFNC； under close monitoring if they are intolerant of NPPV.

Chronic obstructive pulmonary disease (COPD) with mild to moderate hypercapnia (pH > 7.25): HFNC can be used as one of the options for initial respiratory support; Patients who are intolerant of NPPV are advised to use HFNC；. HFNC； is not recommended for patients with pH < 7.25;

After extubation with mechanical ventilation: Patients who have been intubated for more than 24 hours and have high risk factors of respiratory failure after extubation should use HFNC instead of COT； after extubation; Patients with sequential NPPV after mechanical ventilation extubation should continue to use NPPV. If they are intolerant of NPPV, it is recommended to use HFNC；.

After surgery: High-risk and/or obese patients undergoing cardiac or thoracic surgery should use HFNC instead of COT immediately after surgery to reduce the need for re-intubation and respiratory support upgrade; Routine use of HFNC； is not recommended for patients after abdominal surgery.

Pre-oxygenation of tracheal intubation (providing oxygen to patients before tracheal intubation to maintain the stability of blood oxygen saturation during short-term asphyxia): HFNC； is not recommended for routine application during pre-oxygenation of tracheal intubation; Patients who have received HFNC before tracheal intubation can continue to use HFNC during preoxygenation and intubation.

Bronchoscopy: For patients without respiratory failure, HFNC should be used instead of COT to prevent hypoxemia during bronchoscopy; In patients with acute respiratory failure, HFNC can be used as a substitute for NPPV during bronchoscopy.

In addition, the 2021 edition of expert consensus also lists the application recommendations of HFNC in emergency special populations:

Immunosuppression: HFNC can be used as one of the initial oxygen therapy options for patients with immunosuppression complicated with acute type I respiratory failure. If patients who use NPPV are intolerant of NPPV, they can consider HFNC replacement therapy.

Heart failure: HFNC can be used as one of the initial oxygen therapy options for patients with heart failure, and patients who use NPPV can consider HFNC replacement therapy if they are intolerant;

Carbon monoxide poisoning: HFNC can be used as one of the initial oxygen therapy options for patients with mild carbon monoxide poisoning;

Palliative treatment: HFNC can be used as one of the initial oxygen therapy options for patients with palliative treatment, and patients with intolerance to NPPV can try HFNC.

Let’s talk about the contraindications of HFNC. In fact, the relevant contents of these three guides are similar. The contraindications mainly include:

Cardiac arrest;

Severe type I respiratory failure;

Moderate and severe respiratory acidosis hypercapnia (pH < 7.30);

Combined with multiple organ dysfunction.

three

Parameter setting of HFNC

After talking about indications and contraindications, let’s give you some dry goods and see how to set the parameters of HFNC. Compared with NPPV, HFNC needs to set fewer parameters, mainly including temperature, gas flow and oxygen concentration.

The setting range of temperature is generally 31~37℃, which is mainly adjusted according to the patient’s comfort and tolerance, and at the same time, a certain sputum viscosity is maintained, which makes the sputum easy to cough up.

The setting range of gas flow rate is generally 8-80L/min, and the highest oxygen concentration can reach 100%, which are mainly set according to the type of respiratory failure of patients:

Type I respiratory failure: the initial setting of gas flow rate is 30 ~ 40l/min; Titration of FIO _ 2 to maintain SpO2 _ 2 at 92%~96%, combined with dynamic adjustment of blood gas analysis, if the oxygenation target is not reached, the oxygen flow rate can be gradually increased to increase FIO _ 2 to 100% at the highest;

Type Ⅱ respiratory failure: the gas flow rate is initially set at 20~30 L/min, which is adjusted according to the patient’s tolerance and compliance. If CO2 retention is obvious, the flow rate can be set at 45~55 L/min or even higher, reaching the maximum flow rate that the patient can tolerate; Titrate FiO2 _ 2 to maintain the oxygen saturation (SpO2 _ 2) at 88%~92%, and dynamically adjust it with blood gas analysis.

To put it simply, the difference between type I respiratory failure and type II respiratory failure is that the former has no CO2 retention, and it is only necessary to adjust the oxygen concentration to achieve the oxygenation goal, while the latter has CO2 retention, so it is necessary to adjust the gas flow rate to achieve the goal of CO2 removal, and at the same time, it is necessary to adjust the oxygen concentration to maintain SpO2 in a relatively low constant range.

However, the use of HFNC does not mean that you can sit back and relax. It is necessary to closely monitor and identify patients who do not respond well to HFNC treatment as soon as possible to avoid delaying the upgrade of respiratory support and worsening the clinical prognosis. The consensus of experts in the 2021 edition points out that:

During the first 1-2 hours of HFNC, close observation should be made. If there are any failure prediction indicators (respiratory rate > 35 beats /min, SPO2≤88%, the ratio of SPO2/FiO2 to respiratory rate (ROX index) < 2.85, contradictory movements of chest and abdomen or use of auxiliary respiratory muscles, etc.), respiratory support should be upgraded in time (NPPV or invasive ventilation).

If the respiratory condition is still not improved after 48 hours of using HFNC, there are still any of the above predictors of failure, or the ROX index is gradually decreased, or the hemodynamics is unstable, it is regarded as a failure of HFNC treatment, and it is recommended to upgrade to invasive ventilation.

So when can the HFNC be removed? According to the consensus of experts in 2019, the parameters of HFNC will be gradually reduced after the primary disease is controlled. If the following criteria are met, the HFNC can be removed: inspiratory flow < ＜20L/min and fio2 < 30%.

On this basis, the 2021 edition of expert consensus recommended the specific process of evacuation of HFNC: during the evacuation of HFNC, it is suggested to reduce FiO2 first, and then reduce the gas flow rate. When the gas flow rate is reduced to 15L/min, stop using HFNC and change to COT.

Nowadays, the first thing for consumers to buy a car is to see whether this car is rich in configuration, and it is no exception to nature. Let’s take a look at its performance.

First of all, from the appearance, the Mercedes-Benz E-Class plug-in hybrid front has taken a beautiful route and is very recognizable. Coupled with the stocky headlights, the details are exquisite. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Coming to the side of the car body, the size of the car body is 5092 mm * 1880 mm * 1489 mm. The car adopts fashionable and simple lines, and the car body looks very calm. With large-sized thick-walled tires, the shape is quite solid. In the rear part, the overall shape of the Mercedes-Benz E-Class plug-in hybrid rear echoes the front of the car, and the taillights present an avant-garde personality design style, creating a good gas field.

In terms of interior, the interior presents a stable and atmospheric design style, giving people a very solid feeling. The steering wheel design of the car is very elegant, made of leather and comfortable. From the central control point of view, the 14.4-inch central control screen is used for decoration, which makes the interior design quite layered and meets the aesthetic standards of most consumers. Let Xiaobian introduce the dashboard and seats. The dashboard design is remarkable and very eye-catching. The car adopts imitation leather seats, which are wide and thick, and the overall comfort and wrapping are not bad.

Mercedes-Benz E-Class plug-in hybrid trunk is quite satisfactory in space performance, but it supports the rear seats to be laid down, which greatly improves the expansion of space and meets the daily travel needs. In addition, the car is equipped with fatigue warning, anti-lock braking (ABS), LED daytime running lights, brake assist (EBA/BAS, etc.), braking force distribution (EBD) main driving airbag, co-pilot airbag, knee airbag, side airbag curtain, front side airbag and other safety configurations.

Do you have a lot of ideas after reading today’s story? This class of cars can often give consideration to both cost performance and practicality, and is often considered by most consumers as the first choice when buying a car.

I. Market Sales Performance

■ Sales of new energy vehicles decreased month-on-month, and the proportion of smart cars reached a new high.

　　In February, the retail sales of passenger car market was 1.095 million, down 21.0% year-on-year and 46.2% quarter-on-quarter. The retail sales volume of the new energy vehicle market was 388,000 vehicles, down 11.6% year-on-year and 42.1% quarter-on-quarter. In February, the domestic retail penetration rate of new energy vehicles was 35.8%, which was 2.9 percentage points higher than that in January, but only 3.8 percentage points higher than that of 32.0% in the same period of last year. The year-on-year increase of penetration rate narrowed, so it is inevitable for car companies to launch a new round of "price war" to compete for the stock market at this moment.

　　Qin PLUS, who took the lead in price reduction in February, won the new energy sales list, while Tesla’s Model Y and Wenjie M7 () ranked second and third in the sales list. In addition, BYD’s five cars, namely Seagull, Song PLUS New Energy, Song Pro New Energy, Dolphin and Yuan PLUS, ranked in the top ten in the sales list. In addition, Hongguang MINIEV and Ideal L7 ranked sixth and ninth in the sales list. Due to the overall decline in sales in February, only the top six cars on the list sold more than 10 thousand.

　　In February, Top 5 smart car brands were BYD, Tesla, AITO Wenjie, LI and Weilai. Among them, BYD’s market share continued to decline by 1.8 percentage points month-on-month, accounting for 17.4% of the total sales of smart electric vehicles. AITO ranks third in the list of smart car hot-selling brands, surpassing LI. In February, the sales of Weilai and Extreme Krypton dropped slightly, ranking fifth and sixth among the best-selling brands of smart cars.

　　Looking at the sales rankings of various cars of smart electric vehicles, Model Y returned to the top of the list, while M7, which had the highest sales volume last month, ranked second with a gap of more than 1,000 vehicles, and they formed the first echelon of smart electric vehicle sales. Ideals L7, L8 and L9 rank third, fifth and eighth in the smart sales list. BYD only entered the top ten of the smart car sales list with three cars: Han, Song Pro New Energy and Song L. Competing in the stock market, BYD is bound to be intelligent. In the 2024 Dream Day held on January 16th, Wang Chuanfu, chairman of BYD, once revealed that "BYD will invest 100 billion yuan in the field of intelligence in the future, leading the development direction of new energy vehicles along the technical route of vehicle intelligence."

■ The sales volume of smart plug-in hybrid cars has dropped significantly.

　　In February, the sales volume of smart electric vehicles decreased by 40.4% from the previous month to 208,000 units. The sharp drop in overall sales has an impact on the proportion and pattern of various vehicle categories. Among them, the sales volume of smart plug-in hybrid vehicles declined the most, with the sales volume falling to 55,000, which was the same as that of intelligent extended-range vehicles. This is directly related to the decline in BYD sales last month. In addition to Qin PLUS new energy, BYD’s Song Pro new energy, Song PLUS new energy, Tang New energy, Han New energy and other car sales all showed a significant decline.

　　In terms of models, the sales of smart electric vehicles of all models declined in February. Among the cars that have sold more than 2,000 vehicles, the sales of Qin PLUS, which has just reduced its price, have increased, and only the sales of Wei brand Lanshan DHT-PHEV have increased slightly in SUV models. The intelligent MPV model saw the biggest decline, with the sales volume falling to 4.3%, and only 0.9 million vehicles were sold. In February, the sales volume of Tengshi D9 decreased by 50% month-on-month. Tucki X9, which just went on the market, ranked second in the sales list of intelligent MPV models, but it was only about one third of the sales volume of Tengshi D9.

Second, the heat of automobile consumption

■ The proportion of new energy concerns has reached a new high, and the proportion of smart cars has dropped.

　　According to car home Big Data, the proportion of attention to new energy sources rebounded in February, up 2.0 percentage points from the previous month, the highest level in history since statistics. The proportion of people concerned about smart electric vehicles declined, down 2.1 percentage points from the previous month to 64.1%. In the meantime, we can see that new energy vehicles with low proportion of smart driving configuration have received more attention this month. Among them, the representative models are Qin PLUS and destroyer 05, both of which have increased their attention by more than 200%.

■ New energy vehicles: The popularity of mainstream brands in China increased year-on-year

　　In the overall new energy market, except for the mainstream brands in China, the proportion of attention of other brand types has decreased. The proportion of attention of mainstream brands in China increased by 6.6 and 1.8 percentage points year-on-year to 58.4% respectively. Among them, the number of followers of BYD’s various cars represented by BYD Qin PLUS has greatly increased. In addition, the attention of Wuling Xingguang, Chang ‘an Qiyuan A05 and Deep Blue SL03, which also responded to the price adjustment, has also been greatly improved.

　　In terms of specific brands, among overseas mainstream brands, Honda and Toyota are equally concerned, and Kia ranks fifth in the attention list with the newly listed 2024 EV5. Among China’s new power brands, Weilai’s 2024 full-range models went on the market, helping Weilai surpass Tucki and rank third in the attention list. Among the mainstream brands in China, BYD’s attention proportion increased by nearly 10 percentage points from the previous month to 35.0%.

■ Smart cars: The popularity of mainstream brands in China increased year-on-year, while that of Tesla decreased year-on-year.

　　In the smart electric vehicle market, the proportion of attention of mainstream brands in China also increased by 7.2 and 0.5 percentage points year-on-year to 47.7%, which was higher than that in the overall new energy market, but lower than that in the overall new energy market. It not only reflects the long-term trend of improving the intelligence level of mainstream brands in China in the past year, but also shows the short-term strategy that mainstream brands in China take the lead in launching a "price war" on low-priced models to get attention.

　　In terms of specific brands, among the new power brands in China, Gaohe Automobile, which announced the suspension of production, ranked fifth in the attention list, mainly because of the negative news that attracted onlookers, and the number of followers of its several models increased by more than 70% month-on-month. Among the mainstream brands in China, Tengshi D9′ s 2024 model went on the market, and Tengshi rose to the third place in the attention list.

■ Medium-sized cars pay attention to the decrease in heat, while medium-sized and large MPVs pay attention to the increase in heat.

　　In terms of vehicle types, in the overall new energy market, the proportion of year-on-year attention of mini-cars and medium-sized cars has declined. Although the proportion of compact cars decreased by 0.3 percentage points year-on-year, it increased by 2.9 percentage points month-on-month, reaching the same level as medium-sized cars and medium-sized and large cars, and the proportion of all three was around 11%.

　　Compact cars are the main battlefield of this round of "price war", and the models with the largest increase in the proportion of concern are BYD Qin PLUS, destroyer 05 and Changan Qiyuan A05. The popularity of medium and large MPVs continued to increase, increasing by 1.9 and 0.2 percentage points year-on-year to 4.5% respectively, among which the number of followers of Tengshi D9, Lantu Dreamer and other cars increased greatly.

　　Looking at the smart electric vehicle market, the attention proportion of medium-sized cars has dropped the most in the past year, with the decline of attention of Tesla Model 3, BMW i3 and Tucki P7 as the representatives. The medium-sized and large SUVs and large SUVs have the highest year-on-year increase in attention. These two types of vehicles have high intelligent configuration rate, leaving a large room for China brands to increase. Among them, the successful performance of ideal L series, Wenjie M series, Wangwang U8 and tank new energy in the market is enough to prove it.

■ AITO asked the world to surpass Tesla and ranked first in the attention of new forces.

　　In February, Tesla’s attention was surpassed by China’s new power brand AITO for the first time. It can be seen from the top ten hot cars of new power brands that Tesla is wrestling with the world of inquiry, with M7 and M9 in the first and fourth places respectively, while Tesla’s Model Y and Model 3 are ranked second and third, and M5 is ranked eighth in the world of inquiry. Weilai once again surpassed Tucki with the listing attention of all the 2024 new models, and the former "Wei Xiaoli" has now become the second echelon of the new power attention list. In February, the top ten hot cars were Zero Run C11 and Aouita 12.

Third, intelligent product analysis

■ In February, 138 new energy vehicles were launched, and smart new vehicles accounted for 69.6%.

　　In February, 138 new cars were launched by New Energy, and the number of new cars listed decreased by 2.1% year-on-year and increased by 29.0% quarter-on-quarter. In February, the intelligent allocation rate of new cars listed on the market increased from the previous month, with a total of 96 smart new cars listed, accounting for 69.6%. The new car comes standard with L2 intelligent driving capability, and the lowest price is the 2024 Longteng version of 1.5TD-DHT Pro 100KM excellent model of Geely Emgrand L HiP, with a guide price of 99,800 yuan; The highest price comes from the first limited edition of the 2024 Hi4-T from Tank 700 New Energy, with a guide price of 700,000 yuan.

■ In February, the overall level of intelligent configuration of new cars rebounded.

　　The intelligent configuration level of new cars listed in February was 69.6%. With the penetration of autonomous driving technology into low-priced vehicles and the gradual landing of advanced self-driving technology, it is estimated that the overall L2-class self-driving function of new vehicles will account for about 60% in 2024. At the same time, in addition to the intelligent basic configuration, the intelligent networked car will pay more attention to the user experience and provide more intelligent and personalized services, such as intelligent suspension system, high-level cognitive intelligent cockpit and smarter voice assistant.

■ All new cars listed above the price of 200,000 basically realize L2 self-driving configuration.

　　　The following figure analyzes the distribution of new cars and smart new energy vehicles in each price range. Among the new energy vehicles listed in February, one new car with a price below 100,000 has reached the smart car standard. The most new models are listed at the price of 100,000-200,000, and the intelligent configuration rate has reached 58.2%. Only one car with a price of more than 200,000 yuan has no L2 self-driving configuration as standard. The average guide price of new smart cars listed was 272,000 yuan, and the median was 210,800 yuan, both of which were lower than last month.

Fourth, the market price trend

■ The new model of Krypton 001 went on the market, and the weighted quotation rose; The new destroyer 05 comes on the market, and the starting price is lowered.

　　In February, the top five cars with the weighted price increase in the smart electric car market were: Extreme Krypton 001, Yuanhang Y6, Toyota bZ3, Baojun Yunduo and Panamera New Energy. The increase in the weighted quotation of Krypton 001 is due to the launch of new models and the increase in the number of clues of high-priced models. Yuanhang Y6 is due to the fluctuation of weighted quotation caused by the unstable clues of various price models just listed in December last year.

　　The top five cars whose weighted selling prices have dropped are: Destroyer 05, Mercedes EQS, Changan Qiyuan A05, Nezha S and BMW i7. The decrease of the weighted selling price of destroyer 05 and Chang ‘an Qiyuan A05 was affected by the official downward adjustment of the guiding price in this round of "price war". The decline in the weighted selling price of Mercedes-Benz EQS is due to the dealer’s downward adjustment of the quotation.

■ Mercedes-Benz EQC dealer quotation is raised; The new Buick E4 model is on the market, and all the prices are reduced.

　　Among SUVs, the top five cars with weighted price increases are: Mercedes-Benz EQC, Lexus UX New Energy, BMW iX3, Kia EV5 and Roewe RX5 eMAX. The increase in the weighted selling price of Mercedes-Benz EQC is due to the dealer’s upward quotation. The increase in the weighted selling price of Lexus UX new energy is also due to the increase in the dealer’s quotation, and the proportion of clues of high-priced models has increased.

　　The top five cars whose weighted selling prices have dropped are Buick E4, Jennisys GV60, Audi Q4 e-tron, Audi e-tron (imported) and Yuanhang H8. Buick E4 is also a participant in this round of "price war". The price of the new Buick E4 has been adjusted, with a decrease of 27,000-30,000 yuan, which has brought down the weighted selling price. The main reason for the decrease in the weighted selling price of GV60 is that the dealer has lowered the quotation, and the distribution of clues of different price models fluctuates due to the launch of new models.

　　After the Spring Festival, the automobile market was swept by a vigorous wave of price reduction, and 2024 will be a crucial year to determine the future market structure. Car companies grit their teeth and make efforts at the same time in price control and intelligence level. In 2024, the intelligent networked automobile industry will continue to grow, and the growth space will shift from "quantity" to "quality" and "new". Technological innovation and policy support will be the key factors to promote the development of the industry. When the competition in the new energy automobile market shifts from incremental market to stock market, the competitiveness of automobile enterprises will be more reflected in the intelligent level.
