Introduced the supermarket. This system uses natural working -quality carbon dioxide instead of traditional refrigerants such as Flion, to achieve low temperature refrigeration and waste heat recovery. Within one month after the new system was launched, supermarkets such as supermarkets and Metro saved electricity costs exceeding 15%.

In fact, this is just a small example of Peking University's concentrated advantages in carrying out scientific research and serving major national strategic needs. In the past five years, the school has been approved by 134 key projects of the National R & D Plan, 3497 National Natural Science Foundation Projects, and 258 National Social Science Fund Projects. As the first completion unit, 18 National Science and Technology Awards have been won.

Service capital development

Use carbon dioxide cold chain to eliminate new coronal virus

"For a long time, the use of wider use and more mature technology on the market is Flun, but its damage and impact on the ozone layer on the ozone layer are irreversible." Zhang Xinrong said that the team deeply cultivated the new type of refrigeration and heating thermodynamic cycle. For many years, the breakthrough port was finally found on natural working -quality carbon dioxide. The remaining heat generated by refrigeration was used to maintain the operation of heating, hot water, and lighting through the hot and cold integrated system.

Initially, the scientific research project was tailored for the Beijing Winter Olympics. During the Winter Olympics, athletes of various countries created 10 Olympic records and 1 world records on the national speed skating "ice ribbon" of 12,000 square meters. This system that created the "fastest ice" was the system.

"The larger the area, the more difficult it is to ensure the uniformity of the ice surface temperature. If the anti -freezing solution is used to refrigerate it, the temperature of the ice surface will be uneven due to the different local temperature. Environmental protection. "Zhang Xinrong said that the use of carbon dioxide as refrigerant can help the Winter Olympic ice -saving more than 50%.

The Beijing Winter Olympics ended successfully, and Zhang Xinrong's team's exploration did not stop. The team proposes that the use of liquid carbon dioxide to dissolve the new coronal virus coating film, thereby achieving the role of eliminating disinfecting.

"You can imagine the coating film as a layer of skin. The virus will lose its activity without the protection of the skin, thereby reducing the infection of fresh food in cold chain transportation." Zhang Xinrong revealed that at present, China Customs, China -Europe Railway and other related departments are Active docking with the team, this theoretical research is expected to land in the future not far and contribute to agricultural product safety logistics under the epidemic.

Strengthen the construction of scientific and technological innovation bases

Huairou Science City multi -mode imaging facilities will be completed

Huairou Science City is in full swing, and researchers at Peking University are also working hard. At present, the multi -mode cross -scale biomedical imaging facility project, which is led by Peking University, has basically completed the work of facade decoration, indoor decoration, mechanical and electrical installation, and outdoor paving greening. It will usher in the completion acceptance in August. The project will promote the "Chinese creation" of high -end biomedical image equipment and crack the mystery of life and disease. Beijing Laser Accelerating Innovation Center's construction project construction main structure has also been completed, which will be tried in October next year. Here we will have key technologies for advanced process devices and characteristic technology to promote the high -quality development of the integrated circuit industry.

Not only is it actively integrated into the construction of the Beijing National Science and Technology Innovation Center and the International Science and Technology Innovation Center, Peking University also actively participates in the construction of the national laboratory system with the national laboratory as the core. Software engineering, video and visual technology, oral biomedical materials and digital diagnosis and treatment equipment: three national engineering research centers were allowed to be included in the new sequence management, key core technologies for the "card neck", and promoted the deep integration of the innovative chain industry chain.

"Mix and match" stimulates a new paradigm of scientific research

New methods of genetic diagnosis are rescued millions of defects per year

In recent years, Peking University has played the advantages of basic research and discipline cross -integration, and continuously increased the research and development of major cross -area such as "clinical medicine", "carbon neutralization", and continued to stimulate A new paradigm of scientific research realizes the source innovation of "from 0 to 1".

Clinical research on brain diseases, sample library platforms, environmental protection atmospheric oxygen pollution prevention, stem cell regeneration medical technology ... A series of key technologies related to people's livelihood have made major breakthroughs and progress. Academician Qiao Jie, Xie Xiaoliang and Professor Tang Fuhui team for the first time created a new method of new embryo with higher cost, high efficiency and higher accuracy. The problem of reproductive health brings the hope of breeding a healthy life for millions of birth defects in my country each year. After the outbreak of the new coronary pneumonia, Peking University Beijing Future Gene diagnosis High -precision Innovation Center played the technical advantages of the frontier fields such as single -cell genome sequencing technology and gene editing technology. , Won the "advanced collective of the national science and technology system against the new crown pneumonia."

Facing the future, Peking University will always adhere to the national strategy, implement the various planning and deployment of the school's "Fourteenth Five -Year Plan" scientific and technological innovation, and take the opportunity of the 14th party congress of the school to strive to cross -integrate basic research and disciplines and disciplines. The advantage of the maximum extent is to the greatest extent to lead the construction of high -level research universities and strengthen the power of national strategic technology forces, and contribute to the construction of service technology and the realization of high -level technology independence and self -reliance.
