Among the oil and gas projects with the highest proportion downstream of aerogel in China, aerogel is mainly used as external thermal insulation material for energy infrastructure and thermal insulation material for natural gas pipelines, which can save space, improve construction efficiency by about 30%, and save energy and maintenance costs. Under the background of the rapid development of domestic refining and chemical industry, the market demand of aerogel will usher in the growth space. In the aspect of transportation, because the aerogel is lighter and has good flame retardant performance, it can effectively solve the problem of battery thermal runaway. According to the 2022 Aerogel Industry Research report of the National New Materials Industry Development Strategy Advisory Committee, the use of aerogel flame retardant materials in the battery core module of new energy vehicles can improve the high temperature resistance of the battery package to more than 800℃. With the rapid development of new energy vehicle market, the demand for aerogel is expected to continue to increase. In addition, aerogels also have broad market prospects in building materials, clothing and other aspects.

The heat preservation work of the joint is carried out at the steel pipe engineering site, including the installation of the outer casing of the joint, the connection and sealing of the outer casing of the joint with the supervisor and the foaming of the joint on site, but does not include the welding of the joint part of the steel pipe. High temperature prefabricated directly buried thermal insulation pipe not only has advanced technology and practical performance incomparable with traditional trench and overhead laying pipeline, but also has remarkable social and economic benefits, and it is also an effective measure for heating and energy saving. The high temperature prefabricated directly buried heat preservation pipe adopts the technology of directly buried heating pipe.

It includes the installation of the joint outer casing, the connection and sealing of the joint outer casing with the supervisor and the foaming work of the on-site joint, but does not include the welding of the steel pipe of the joint part. (1) sleeve joint, in this way, the joint casing is made of the same material as the prefabricated thermal insulation pipe casing, and the polyethylene casing with density is connected and sealed by heat shrinkage belt between the polyethylene joint casing and the main pipe to ensure the watertightness of the joint. Then the joint foaming is carried out on the foaming hole on the joint casing, and after the foaming is completed, the foaming hole is sealed by patch or hot melt welding.

It is reported that the FDA Advisory Committee supports the proposal, believing that the COVID-19 vaccine can be updated every year to match the epidemic strain, so as to better protect the people. However, there is a debate in academic circles, and some scholars believe that the proposal can simplify the national policy on the prevention and treatment of COVID-19, thereby increasing the vaccination rate, while some scholars have reservations about whether the current data results support the annual update of vaccines. Some scholars have pointed out that “the speed at which novel coronavirus produces new variants is different from that of influenza.” the annual update is not necessarily feasible, and there is no evidence as to whether people need to be vaccinated every year or less frequently in order to be protected. On the other hand, some scholars disagree with the timing of the FDA plan to be updated every autumn, because the COVID-19 epidemic not only has the trend of surge in winter, but also has a certain outbreak wave at the end of summer, or the vaccine should be updated and vaccinated earlier.

The application scene of “Fuchun Mountain House Brand Hall” brings the government procurement of agricultural and sideline products in Fuyang into the “cloud era”, injects new momentum into the revitalization of rural industry, and has been praised by domestic experts and scholars. Zhang Zhian, director of Guangzhou Live E-commerce Research Institute and professor of Fudan University, believes that it is of positive significance to take the “Fuchun Mountain House Brand Pavilion” as the hub to promote the e-commerce operation of agricultural products with local characteristics. Zhong Weijun, professor and doctoral supervisor of the School of Public Administration of Zhejiang University of Finance and Economics, said that the experience of “Fuchun Mountain residence Brand Pavilion” is of great value to the revitalization and common prosperity of rural industries, and is also the future direction of modern agricultural development, which is worthy of in-depth study and promotion.
