　　　　　　 CCTV News:The 10th China Conference on Chronic Diseases Management closed yesterday (15th). The reporter learned from the conference that the threat of chronic non-communicable diseases to human beings is becoming more and more serious. According to the statistics of the World Health Organization in 2018, the number of deaths caused by chronic diseases in the world is about 41 million every year, and the situation of prevention and control of chronic diseases in China is not optimistic, and chronic diseases have become the number one killer endangering national health.

　　　　　　 Wang Chen, dean of Peking Union Medical College, China Academy of Medical Sciences, said: "Chronic diseases are short for chronic non-communicable diseases, and the World Health Organization calls them four chronic diseases, namely cardiovascular and cerebrovascular diseases, tumors, chronic respiratory diseases, diabetes and metabolic diseases. Internationally, chronic diseases account for 87% of human deaths, and China accounts for 86%, which means that 86% of Chinese’s deaths are caused by chronic diseases. "

　　　　　　 According to experts, chronic non-communicable diseases are related to overweight, obesity, long-term overeating, insufficient exercise, nutritional imbalance, smoking and drinking, viral infection, autoimmune and other factors. Mental stress and emotional depression are often easy to cause a variety of chronic diseases, which are often ignored by people because of their own characteristics, which is also the main cloud cause of high incidence of chronic diseases in recent years.

　　　　　　 Wang Chen: "It doesn’t happen immediately after infection, like infectious diseases, so it makes patients suffer invisibly and unconsciously, which is an important feature of chronic disease." The more so, the more it deserves our attention in our daily life, and it is extremely prominent and important for China people to correct their bad habits. "

　　　　　　 Experts say that chronic diseases are treated in hospitals and prevented in individuals. At present, it is the focus of chronic disease prevention and treatment in China to guide people to seek medical treatment scientifically, use drugs rationally and change their lifestyle. Experts say that the treatment of chronic diseases is a systematic project, and scientific medical treatment and rational drug use are an important link in the treatment of chronic diseases.

　　　　　　 Weng Jianping, Executive Dean of School of Clinical Medicine, China University of Science and Technology: "It may be a combination of many diseases. For example, a person may have hypertension, hyperlipidemia, diabetes and other mental health diseases at the same time, so it is very necessary for doctors to identify the characteristics and problems of this patient, including the causes."

　　　　　　 Experts suggest that chronic diseases, as a kind of diseases coexisting with living habits, and their related risk factors are common in the population. Therefore, developing a healthy lifestyle is the focus of prevention and control of chronic diseases.

　　　　　　 Weng Jianping, Executive Dean of School of Clinical Medicine, China University of Science and Technology, said: "For ordinary people or most people, if they have no genetic background, I believe that a healthy lifestyle, including proper exercise and light diet, with less salt and less oil, is the most basic thing to do. In particular, the education and improvement of young people’s lifestyles and working methods is one of the most important, effective and direct factors to prevent chronic diseases. "

　　　　　　 Research shows that mental health problems will increase the risk of chronic diseases, and effective psychological intervention is not only an effective means to prevent and control chronic diseases, but also plays a positive role in the rehabilitation of patients.

　　　　　　 Studies have shown that serious mental health problems can induce a variety of chronic diseases. In China, 16%-17.5% of adults suffer from depression, but most people with mental disorders never seek help from mental health or psychologists, thus increasing the risk of chronic diseases.

　　　　　　 Peng Kaiping, Dean of Tsinghua University Academy of Social Sciences, said: "If our mentality is not good, long-term stress, long-term depression and anxiety can all cause cardiovascular diseases and endocrine disorders, and our various immune systems will be hurt, including our gastrointestinal problems, including our sleep, pregnancy, emotional activities, memory and actions."

　　　　　　 Studies have shown that 50-70% of patients with chronic diseases such as malignant tumors suffer from depression and 40-50% from anxiety, which not only destroys the normal physiological function of the body, but also causes emotional reactions such as pain, anxiety, depression, fear and despair, and even refuses treatment. So timely psychological intervention is particularly important.

　　　　　　 Zhang Minghui, director of the Institute of Cytology, Tsinghua University Clinical Medical College, said: "For some diseases that cause serious psychological problems, such as cancer patients, in addition to drug treatment or after drug intervention, we can create a relaxed and good living environment or working environment for them in time, which is very valuable for the rehabilitation of these chronic diseases. In modern medicine, we can use scales or modern testing to give an objective qualitative or evaluation."

　　　　　　 Experts point out that psychological intervention can help people with mental health problems get personalized help to cope with some health risks faced by their bodies and reduce the probability of chronic diseases.

　　Comparison of spike protein mutation between Delta strain and Omicron strain (picture from Rome Children’s Hospital)

　　■ On November 27th, local time, the research team of Rome Children’s Hospital released the world’s first picture of Omicron, a new mutant strain of Covid-19.

　　■ The picture shows that compared with Delta strain of COVID-19 mutant virus, Omicron strain has more spike protein mutations. These variations are diverse, and most of them are located in the areas that interact with human cells.

　　■ Researchers say that Covid-19 has adapted to the human body through mutation, but it doesn’t necessarily mean that it has become more dangerous.

　　The first case of Omicron virus infection occurred in Italy.

　　On November 27th, local time, Italy confirmed the first case of Covid-19 mutant strain Omicron infection by laboratory sequencing. Italy’s "Corriere della Serra" reported that the patient lived in Campania region in southern Italy and returned from a trip to Mozambique. He had previously tested positive for Covid-19 and was isolated, and now he is in good health.

　　On November 26th, local time, the Italian Ministry of Health has decided to ban people who have stayed in eight African countries including South Africa and Zimbabwe in the past 14 days.

　　Peter Hotz, a professor at Baylor Medical College in the United States, said: "We often lack mobility in the process of sequencing virus genes, so I wouldn’t be surprised at all if the new mutant has spread to the United States."

　　Where did the mutant strain come from?

　　Researchers are studying it.

　　With the spread of Omicron mutant, researchers are also studying where it came from. Franç ois Balu, a professor of biology at University College London, UK, said that Omicron mutant carries a series of unusual mutations, which may occur during the chronic infection of an immunocompromised patient or may come from an untreated AIDS patient.

　　Risk assessment of new mutant

　　More experimental data are still needed

　　Compared with Delta virus, where is the greater danger of the mutant strain "Omicron"? Will it trigger a wider spread?

　　According to Russian TV today, at present, Omicron mutant is spreading in Africa and outside Africa at an alarming rate.

　　Take South Africa as an example. Recently, 90% of the newly infected cases in gauteng province, South Africa are related to this mutant. Many western media believe that Omicron mutant is the most dangerous Covid-19 mutant in the world.

　　The researchers said that the Delta mutant strain discovered in India last October contained a total of 15 mutations, and the World Health Organization listed it as a "mutant strain that needs attention" in May this year; According to the preliminary study, the Omicron mutant, which is also listed as a "mutant that needs attention" by WHO, has more mutations than the Beta strain. At present, it is known that the mutant carries at least 32 mutations, which means that the effectiveness of the existing COVID-19 vaccine may be weakened and it may be more infectious.

　　WHO officials said that at present, little is known about this new mutant strain, and more experimental data are still needed to evaluate whether it is more infectious or more resistant to vaccines.

　　Who asks countries

　　Strengthen monitoring and sequencing.

　　How to prevent and control the new Covid-19 mutant? At present, the World Health Organization has asked countries to strengthen the monitoring and sequencing work, and called on countries to strengthen the monitoring and sequencing of all COVID-19 mutant strains that are still prevalent, submit the complete virus genome sequence and metadata to the public database, and report to WHO the initial cases or case clusters related to any mutant strains that need attention.

　　WHO also suggested that international cooperation should be carried out to better understand the various impacts of the mutant strains that need attention through field investigation and laboratory evaluation.

　　At the same time, some countries are worried that this new mutant strain will trigger a new wave of fierce epidemic after the Delta strain. Up to now, about 20 countries have issued or are preparing to issue entry restrictions for flights and passengers in southern African countries.

　　Foch/

　　Omicron strain

　　Or has existed in the United States and has not yet been discovered.

　　According to a report by CNN on November 27th, local time, Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said that Covid-19 mutant strain Omicron may have appeared in the United States, but it has not been discovered.

　　The U.S. Centers for Disease Control and Prevention said on November 26th that so far, no known cases of Omicron strain infection have been found in the United States. If the mutated strain appears in the United States, the U.S. Centers for Disease Control and Prevention expects to quickly confirm the cases through the monitoring system.

　　US President Biden announced on November 26th that the United States would restrict the entry of tourists from South Africa, Botswana, Zimbabwe, Namibia, Lesotho, Swaziland, Mozambique and Malawi from November 29th.

　　Influenced by Omicron strain.

　　The US government advised people not to travel to eight African countries.

　　On November 27th, local time, affected by Covid-19 mutant strain Omicron, the Centers for Disease Control and Prevention (CDC) upgraded the travel risk index of eight African countries, namely South Africa, Zimbabwe, Namibia, Mozambique, Malawi, Lesotho, Swaziland and Botswana, to "level 4", which means "very high".

　　On the same day, the State Council also issued a warning to the public, suggesting not to travel to the above eight African countries.

　　Zhong Nanshan, Zhang Wenhong and Wu Zunyou voiced/

　　Omicron strain poses more challenges to epidemic prevention.

　　According to the Southern Plus, Zhong Nanshan introduced in an interview on November 28th that from the current situation, the Omicron mutant has spread rapidly, and it has been popular in South Africa and other regions, and cases have been found in Hong Kong, China recently. "This mutant is very new. Although molecular genetic testing has found that it has many changes in the receptor binding site, how harmful it is, how fast it will spread, whether it will make the disease more serious, and whether it needs to be targeted. Vaccine research and development depends on the situation. It is too early to draw conclusions. "

　　Zhong Nanshan said that it will take some time to judge the harmfulness of Omicron mutant, and we need to pay attention to it at any time, but we won’t take any big action yet. "There is also a need to pay more attention to the prevention and control of personnel from relevant places in South Africa."

　　Earlier, Zhong Nanshan also said on the 27th that there is not much knowledge about this variant virus, but this virus carries a lot of mutations, which also poses more challenges to epidemic prevention.

　　At noon on November 28th, Zhang Wenhong also issued a Weibo to respond to the influence of the new mutant strain. Zhang Wenhong said that it can be judged that the emergence of the mutant virus in South Africa is accidental, but it will take about two weeks to observe whether it will pose a threat to the current fragile population immunity.

　　According to the Beijing News, on November 28th, Wu Zunyou, chief epidemiologist of China Center for Disease Control and Prevention, said that the epidemic situation is the most serious in the world, mainly in Europe, and the prevalent strain this winter and next spring is mainly Delta. Whether the mutant strain Omicron can develop into the dominant strain needs further close observation.

　　Wu Zunyou said that Omicron, a mutant strain discovered in South Africa, is a new mutant strain, with more mutation sites than the previous ones, reaching 32 mutation sites. The mathematical model shows that Omicron is more contagious than the Bedelta, but no matter how it mutates, public health measures such as wearing masks and keeping social distance are effective for all mutated strains.

　　(Comprehensive Xinhuanet, national business daily)

　　More than 20 countries have taken restrictive measures.

　　The discovery of Omicron strain in South Africa and other countries has aroused great global vigilance. Up to now, the governments of about 20 countries and regions have successively issued or prepared to issue entry restrictions for flights and passengers in southern African countries.

　　Among them, the British government said on the 26th that from that day on, flights from South Africa and five neighboring countries were prohibited from entering the country, and people with relevant travel history were required to undergo nucleic acid testing and isolation. On the same day, Switzerland announced that it would ban all direct flights from Botswana, South Africa and other countries indefinitely.

　　On November 26th, local time, the Italian Ministry of Health has decided to ban people who have stayed in eight African countries including South Africa and Zimbabwe in the past 14 days.

　　German disease control agencies have classified South Africa as a "virus mutation area", and all people who enter Germany from South Africa must be quarantined for 14 days, regardless of whether they have been vaccinated or not.

　　According to the notice issued by Pakistan National Command and Operation Center on November 27th, Pakistan issued a travel ban on passengers from South Africa, Lesotho, Swaziland, Mozambique, Botswana, Namibia and other regions.

　　In addition, Russia also announced that it will ban foreign citizens from South Africa and other countries and regions from the 28th of this month.

　　Health Canada also announced on 26th that it will ban foreign citizens who have been to southern African countries in the past 14 days.

　　Israel has banned its citizens from traveling to southern Africa after discovering new cases of mutant virus infection in its territory. On the 28th local time, Israel decided to ban all foreigners from entering the country, and the ban will last for 14 days.

　　Singapore and Malaysia announced on the 26th that they would ban the entry of passengers who have recently visited seven countries including South Africa.

　　The Indian government has issued a reminder, suggesting that local governments should carry out Covid-19 testing and health screening for international travelers from South Africa and other "risk zone" countries.

　　Japan has also implemented measures to ground inbound flights and isolate passengers for countries such as South Africa. In response to the travel ban issued by many countries around the world, the South African government responded on the 26th that it is harsh and unscientific to impose travel restrictions on passengers from South Africa, which is also inconsistent with the recommendations of WHO.

A few days ago, Chezhi. com obtained a set of official maps of Tucki M03, the first model of MONA series, from Xpeng Motors. The new car adopted a brand-new design and kept the Tucki brand LOGO. It is reported that the new car will enter the market of 100,000-150,000 yuan in the future, and adopt Tucki’s intelligent driving technology.

In terms of appearance, the new car adopts a completely different design from Xpeng Motors. First, the headlights are Y-shaped, which has excellent visual effect and is highly recognizable. In addition, the front face is surrounded by a black front, which adds a lot of sportiness. It is worth mentioning that Tucki M03 still uses Xpeng Motors’s "X" logo, which shows that MONA is not a brand new brand, but a brand new series.

The side design is very simple, using the popular hidden door handle design. It is worth mentioning that there is a very creative small spoiler in the D-pillar area on the side of the new car, and its function has not been revealed yet. In addition, there is no lidar on the roof at present, and a pure vision scheme may be adopted in the future.

At the rear of the car, the new car also uses a Y-shaped taillight, which echoes the headlights. The interior of the taillight is also blackened, and the visual effect is good after lighting.

The interior and power system have not been announced yet. According to people familiar with the matter, the battery supplier of Tucki MONA’s first car includes BYD, and its battery life will exceed 500km. For more news about the new car, the car quality network will continue to pay attention to and report.

The C-130H is a comprehensive improved model introduced by the C-130 family in the 1960s, and it is also the main tactical air transport aircraft of the US military at present.

▲C-130H (Source: UTCAerospaceSystems)

C-130 Hercules (Hercules, a hero in Greek mythology) medium-sized tactical transport aircraft is the most successful, longest-lived (in service in 1956) and most productive active transport aircraft in the United States (with a total production of more than 2,000 aircraft), which occupies a core position in American tactical air transport forces and is also an important auxiliary force in American strategic air transport.

The C-130 is equipped with four turboprop engines, which can take off and land on an unprepared runway. It was originally designed to transport armed forces, medical rescue and cargo transshipment. Later, it evolved into various uses, including air strikes, search and rescue, scientific research, meteorological observation, aerial refueling, coastal patrol, and aerial fire fighting.

Among them, WC-130 is an aviation meteorological observation/reconnaissance aircraft modified from C-130 by the Aviation Meteorological Service of the US Air Force, which can undertake tasks such as atmospheric sampling, artificial rainfall, fog driving and winter storm reconnaissance.

C-130J "Super Hercules"

Number of service: 125

Manufacturer: Lockheed Martin

First flight: April 5, 1996

Performance: the maximum speed is 671km/h and the range is 3334km；; The ceiling is 8615m.

C-130J "Super Hercules" is a four-engine turboprop military transport aircraft, which is a comprehensive update of C-130 "Hercules", including new engines, cockpit and other systems.

In the 1970s, the US military launched a research and development plan to replace the C-130 next-generation transport aircraft, called the advanced medium-range short-field take-off and landing transport aircraft, but the final test result was regrettable. The flight economic benefit of C-130 is too good, and the new aircraft is not good enough to be replaced. Therefore, in the 1980s, Lockheed modified a C-130 to test advanced technology and accumulated background information for subsequent improvement. The testing machine was called the high-tech verification foundation. In the 1990s, the technical inspection data of HTTB became the starting point for developing C-130J, which took over as the latest mass production version after the H-type was discontinued in 1996.

▲C-130J (Source: WikimediaCommons)

Thanks to the upgrade of avionics system, the crew of Model J was reduced to three, and the engine was changed to Rolls-Royce AE-2100D3 turboprop engine. The AE-2100D3 is a derivative of V-22 AE-1107C engine, and a newly designed six-blade propeller-"micro-blade propeller" was adopted, which reduced the fuel consumption and engine consumption by 3.3% compared with ordinary propellers during cruising. Compared with the original model, not only the maximum takeoff weight is increased to 74,400 kg, but also the attack landing weight is increased to 64,400 kg, and the flight speed and combat distance of the C-130J have made remarkable progress.

Air conditioning is a necessary household appliance in summer, and various brands of air conditioners on the market are dazzling. Among them, Gree and Midea are two giants in the domestic air-conditioning field, with high sales volume and market share, and they are also one of the first choice brands in the minds of many people when choosing air conditioners.

So, which air conditioner is better in quality, Gree or Midea? Objectively speaking, air conditioning is a product with very mature technology, and the differences in technology, materials and functions are not obvious on the surface, but there are still obvious differences in the quality performance of air conditioning during long-term use and under various harsh conditions.

Which air conditioner has better quality, Gree or Midea? From the following three aspects, the results are clear at a glance!

Brand strength

Gree is a leader in the domestic air-conditioning industry, focusing on the air-conditioning sector, engaging in differentiation (enhancing added value), with strong research and development capabilities and innovative spirit, excellent product technical performance and high-end brand image, which is deeply trusted by consumers.

Gree air-conditioning takes quality as its life, does not cut corners, has solid materials, strict quality control and durable and reliable products. Gree also owns Zhuhai Lingda compressor independently researched and developed, which is the only air-conditioning enterprise in China with the core technology of compressor.

Midea is a domestic comprehensive development-oriented home appliance enterprise, with complete products, and all kinds of home appliances are ranked in the top, which can occupy a large market share in various fields.

Midea air conditioner is famous for its high cost performance, good product aesthetics, high product innovation and relatively close to the people. Midea has also been committed to the progress of compressors, using gmcc compressors or purchasing Haili, Sanyo and other compressors.

Technical strength

Gree and Midea air conditioners have their own characteristics and advantages in technology.

Gree air-conditioning has performed well in refrigeration and heating capacity, stability, noise control and energy saving efficiency. Gree air-conditioning has a number of patented technologies, such as constant temperature heating, cold outside machine, moving large air deflector, photosensitive sensing and so on. Gree also launched an intelligent cloud platform "Gree+",which can remotely control air conditioners through mobile phones.

Midea’s air conditioners also perform well in intelligent control, self-cleaning function and comfortable air supply. Midea air conditioner has the functions of multi-dimensional cleaning system, ECO energy-saving mode, wide-angle air supply, and direct blowing prevention.

Midea has also launched an intelligent platform "Mercure", which can control air conditioners through mobile phones or voice.

Price–performance ratio

As the two most powerful domestic air-conditioning brands, Gree and Midea have their own advantages in quality. For example, the details of Gree air conditioning are well done, and the cooling copper tube will be slightly thicker than 0.03 cm, which increases the cost, not only improving the heat exchange efficiency, but also enhancing the corrosion resistance.

Take Yunjia series, one of the best-selling models of Gree air-conditioning, as an example, the monthly sales volume of the big 1P hanging machine exceeds 10,000 units, and the applicable area is 10 ~ 15m2. This air conditioner has reached the new first-class energy efficiency standard, and its energy efficiency ratio (APF) is as high as 5.28, with excellent energy-saving performance. Built-in triple energy-saving control technology, refrigerant flow control+temperature and humidity control+comfort control, achieving a balance between energy saving and comfort.

This air conditioner adopts Haili compressor, double-row heat exchanger and electronic expansion valve, which improves the heat exchange efficiency and makes the refrigeration heat up quickly. At the same time, the mute effect is also very good, with 7-speed wind speed optional and 4-speed sleep mode to meet the needs of different life scenes.

This air conditioner also has a detachable air outlet design, plus Gree’s innovative 56C bacteria-cleaning and self-cleaning technology, which makes cleaning and care convenient and quick. But also provides a 10-year warranty service, so that users can use it more safely.

Midea air conditioner is famous for its high cost performance, good product aesthetics, high product innovation and relatively close to the people. Midea’s air conditioner used in low-end machines is indeed worse, mainly reflected in the thickness of ABS inner machine shell and galvanized steel plate of outer machine, but it does not affect the normal service life and firmness.

Midea Fengku New Level Energy Efficiency Variable Frequency Air Conditioning is one of the best-selling models of Midea Air Conditioning. Its price is several hundred yuan cheaper than Gree Yunjia, and its cost performance is high. This air conditioner has also reached the new first-class energy efficiency standard, with an energy efficiency ratio (APF) of 5.27 and a simple and elegant design.

Using full DC frequency conversion system, combined with high-frequency rapid cooling and heating technology, the cooling and heating effect is also very good. The 60-second cooling air outlet reaches 34.5 degrees, and the 30-second cooling air outlet reaches 18 degrees. The built-in intelligent clean high-temperature steam washing function is very cost-effective.

Which air conditioner has better quality, Gree or Midea? From the comparison of the above three aspects, Gree and Midea air conditioners have their own advantages, and there is no absolute good or bad. If you pursue quality and technology and don’t mind the higher price, you can choose Gree air conditioner. If you pursue cost performance and innovation and don’t care much about details, you can choose beautiful air conditioners.

Finally, remind everyone that air conditioners need to be cleaned regularly, especially those that have not been used for a long time. It is recommended to clean them thoroughly before opening them. It is very simple to use a special air-conditioning cleaner. Just spray the foam of the cleaner on the air-conditioning radiator and let it stand for 15 minutes, then turn on the air conditioner and let it automatically cycle and clean, thus eliminating the complicated disassembly and cleaning process.

Professional air-conditioning cleaning agent has the ability to produce rich and delicate foam, which can thoroughly remove the dirt in the gap of radiator without dripping water. After use, wipe off the excess foam and stains with a cloth, and the heat sink will be brand-new.

After use, the cooling effect of the air conditioner has been obviously improved, and the air has become much fresher. I feel that my health has also been guaranteed.

It is not enough to only pay attention to the cleaning of air-conditioning filter screen, because the heat sink is the place to shelter evil people and shelter evil practices! Therefore, cleaning agents must be used to clean the heat sink to ensure the safe use of air conditioners.

Cctv news(Reporter Liu Ruirui, reporter from Wang Xiaoying): On May 11th, the "Emergency Mission 2022" earthquake relief exercise was held in Zhangye, Gansu Province.

The exercise simulated a 7.5-magnitude earthquake in Ganzhou District, Zhangye City, Gansu Province. The epicenter was located in Xindun Village, Xindun Town, Ganzhou District, and Jiayuguan, Jinchang, Jiuquan and Wuwei felt strong earthquakes.

According to the setting, in this exercise, the "earthquake" caused houses to collapse and damage, and a series of secondary disasters occurred one after another … …

A trapped person was successfully rescued, and the fire rescue personnel transferred the personnel.

Under the majestic Qilian Mountains, on the vast Gobi Desert, fire engines lined up in turn, drones vacated and helicopters roared.

Team assembly

Number one: an earthquake of magnitude 7.5.

The exercise simulated a 7.5-magnitude earthquake in Ganzhou District, Zhangye City, Gansu Province. The epicenter was located in Xindun Village, Xindun Town, Ganzhou District, and Jiayuguan, Jinchang, Jiuquan and Wuwei felt strong earthquakes.

Rescuers made wooden supports to reinforce the collapsed building to prevent secondary collapse.

The 7.5-magnitude "earthquake" spread to many places, and a large number of houses collapsed and damaged, and a large number of people were trapped under pressure, resulting in multiple secondary disasters, including partial interruption of roads, electricity, water supply, gas and communication, landslides and collapses in mountainous areas, leakage and explosion in Ganzhou section of the west-to-east gas pipeline, overturning of trains in Europe on Lanzhou-Xinjiang line, damage to the west-to-east power transmission project, a large number of tourists trapped in scenic spots, and some villages formed "islands" & …

Three firemen are rescuing the trapped people under the marking point.

In this exercise, the fire drill scenarios are all based on the rescue scenarios that may occur due to the earthquake.

During the exercise, fire rescue teams from Gansu, Beijing, Inner Mongolia, Shandong, Sichuan, Yunnan, Xizang, Shaanxi, Qinghai, Ningxia, Xinjiang and other places quickly responded to the rally and devoted themselves to the rescue.

Number two: multi-site linkage 1+4+4　　

The exercise venue adopts the "1+4+4" mode, with the main exercise venue in Zhangye, sub-exercise venues in Jiayuguan, Jiuquan, Jinchang and Wuwei, and four outdoor venues according to scenic spots, high-rise, underground and railways.　

Fire-fighting and rescue workers use construction machinery to remove heavy objects and rescue people trapped in commercial markets.

During the whole drill, in order to cope with the great earthquake and catastrophe in the plateau and cold area, the whole drill was displayed in panoramic mode, which was divided into three stages: pulling inspection, command exercise and comprehensive exercise.

The driver was trapped in the simulated derailment of the Central European train, and the fire rescue personnel carried out rescue.

In this drill, several rescue scenarios that may be caused by earthquakes were simulated, among which Zhangye simulated the search and rescue of people buried in collapsed buildings, the derailment and overturning rescue of trains in Central Europe, the leakage and explosion rescue of oil and gas pipelines for west-to-east gas transmission, the destruction and rescue of facilities for power transmission from west to east, the fire fighting and rescue of high-rise buildings and the construction of camps, the trapped tourists in the Grand Canyon in scenic spots, and the trapped people caused by the collapse of scaffolding in the construction site.

Among them, the west-east gas pipeline leaked and exploded, and huge black mushroom clouds rose one after another. Due to serious deformation and tearing, a large number of crude oil leaked from the Tanlan crude oil pipeline, which in turn caused a fire of 3,200 square meters. The situation was critical, and four professional chemical fire fighting and rescue teams rushed to the scene to reinforce the disposal.

In the oil and gas pipeline leakage, huge black mushroom clouds rose one after another, and fire rescue forces rushed to the scene to reinforce the disposal.

The fire-fighting robot is carrying out the rescue of oil and gas pipeline leakage and explosion.

Wuwei, Gansu Province, simulated the emergency rescue scene affected by the earthquake, where a landslide occurred in Maya Snow Mountain, three climbers were trapped in the snow mountain, and one person showed symptoms of temperature loss.

Fire rescue forces wear special equipment for cold prevention and anti-skid to climb 5.8 kilometers of mountain roads and go deep into the snow area to search for missing buried personnel.

The trapped people are being transferred to the temporary helicopter rescue point.

Jiayuguan City has set up an airport emergency landing course, where the airport runway was seriously damaged due to the earthquake, and the ground broke in many places, so that the aircraft hovering overhead could not land normally. Rescuers are covering the airport runway with a foam layer with a high-magnification foam generator, which can increase the emergency landing buffer, reduce the friction coefficient and reduce the deceleration braking force. Jinchang simulated mine accidents affected by earthquakes.

Covering the airport runway with foam layer by using high multiple foam generator.

Houses and oil and gas stations in the living area of refining and chemical plant in Yumen old city of Jiuquan City collapsed and caught fire. Some people were trapped under pressure, some roads were damaged, and power and communication were interrupted.

There are 26 subjects in the exercise, including the rescue of ruins, the capsizing rescue of trains in Central Europe, the leakage rescue of oil and gas pipelines in the West-East gas pipeline, the rescue and transfer of trapped tourists in scenic spots, the fire fighting and rescue of high-rise buildings, the rescue and rescue of people in distress in snowy mountains, etc. The fire rescue team has the courage to take responsibility and overcome difficulties, and participated in a total of 23, which fully reflects the role of the fire rescue team as the "main force" and "national team" of emergency rescue.

From the snowy Maya Snow Mountain, to the vast and colorful Gobi sandbars, and then to the steep Pingshan Lake Grand Canyon, orange figures are everywhere.

Number 3: 2,105 firefighters participated.

A total of 2,105 fire rescue workers participated in the exercise, including 1,533 from Gansu Provincial Fire Rescue Corps and 572 from other teams.

The repair team is repairing the operation.

　In addition to specific rescue drill scenarios, it is also crucial to ensure emergency communication through linkage. With the launch of the "Emergency Mission 2022" practical earthquake relief exercise in alpine plateau, extreme situations such as power outage, communication base station damage and public network paralysis have always tested the emergency communication support capability at the disaster site.

After the disaster occurred, the Qiantu Communication Support Team of Zhangye City Fire Rescue Detachment immediately dispatched on-site reconnaissance, established satellite communication links, and reported the disaster at the first time. The emergency communication support detachment of Gansu Provincial Fire and Rescue Corps quickly dispatched to the disaster area to build a command communication network, and mobilized several adjacent detachments to respond synchronously.

Specially modified 10 military three-generation light and high-mobility "Warrior" off-road vehicles are the backbone of emergency rescue and quick dispatch in this exercise, including rescue and obstacle breaking, troop assault, technical rescue, general shelter, communication command, power supply and other vehicles, which are suitable for all-weather, all-terrain and all-regional rescue, and can reach all areas in the province within 10 hours to strive for the "golden rescue period" to the maximum extent.

Number 4: 56,000 pieces of equipment and 70 rescue dogs.

Rescue equipment has also attracted much attention. This exercise carried 56,000 pieces (sets) of advanced fire fighting and rescue equipment in 9 categories, including composite life detectors, high-frequency rescue and cutting sets, large-flow snow cannon robots, large-scale tethered drones, all life-saving robots in waters, heavy-duty support sets, portable electric demolition tools, and mobile lighting lighthouses.

At the scene, the fire reconnaissance robot dog cooperated with modern equipment such as thermal imaging drone to quickly assist rescuers to master the internal situation of collapsed buildings and find the location of trapped people.

Fire detection robot dog.

Search and rescue dogs shuttled through the ruins.

The terrain of the ruins is very complex, and the collapsed bodies and scaffolding are staggered and uneven. With the command of the search and rescue dog trainer, six search and rescue dogs quickly shuttled through the ruins, and with the detection of the radar life detector, many shallow trapped people were successfully searched in 20 minutes.

It is reported that the investment in this exercise includes 70 rescue dogs from China’s rescue dog mobile detachments in Shandong and Yunnan and Gansu and Qinghai fire rescue corps. The whole process adheres to the combination of human and dog, dog equipment and search and rescue.
