The State Key Laboratory has provided strong support in raising the level of science and technology in our country, enhancing the transformation of scientific research achievements and accelerating the development of various industries. The establishment of China's key national laboratories in various fields will further enhance China's national scientific research strength and overall national strength. instrument Field, our country carried out the construction of state key laboratories and carried out various major breakthroughs.
Recently, the group headed by Prof. Xiaoyun Feng and Prof. Gong Qihuang from the State Key Laboratory of Artificial Microstructure and Mesoscopic Physics (Peking University) proposed a new principle of chaos-assisted rapid photon momentum conversion, realizing the ultrahigh quality factor optical microcavity and The ultra-wideband coupling of nanometer-scale waveguides breaks the limitation that the near-field coupling of the micro-nano optical devices requires phase matching, ie, the conservation of momentum. This new principle can be extended to other types of optical microcavities and other electromagnetic frequency bands and may be used in integrated optoelectronics , Optical networks, quantum information processing and other fields play an important role.
As the birth base of scientific research achievements, the construction work of the State Key Laboratory has always been the focus of our country's attention, especially in recent years, with the continuous improvement of China's economic strength and remarkable achievements in scientific and technological innovation in the country, in order to better carry out scientific and technological innovations And found that our country has set up key laboratories in various fields to meet the huge demand for the development and progress of the industry in our country at present, including laboratories in many fields such as biomedicine, remote sensing science, materials technology, marine biology and environmental monitoring Have been completed, providing strong support for China's science and technology work.
Prior to this, the website of the Ministry of Science and Technology released the 2015 Annual State-Key Laboratory Report, which disclosed the operation of China's national laboratories and key state laboratories. As of the end of 2015, a total of 255 key state laboratories were in operation, Pilot national laboratories 7. In the past two years, the state key laboratory construction work continues to promote, at the same time, the state for the laboratory to optimize the integration work also mentioned to the agenda.
Ministry of Science and Technology, Ministry of Finance and National Development and Reform Commission and other three ministries and commissions recently jointly released the "National Science and Technology Innovation Base optimization and integration program," requires the existing pilot national laboratories, state key laboratories and other national bases and platforms for assessment and assessment by withdrawing, Follow the principle of "less but better", select a new batch of high-level national bases for selection and optimization, strictly select standards and strictly control the scale of new construction. It can be seen that the current state attaches great importance to the construction of state key laboratories and plays an important role in the development of national science and technology.
With the implementation of various national policies and construction programs, many breakthroughs have also been made in the key laboratory of scientific research equipment in our country. Recently, with the help of cryo-electron microscopy, the State Key Laboratory of Membrane Biology has made progress in research. Body frozen in the sample preparation of salt concentration is high, poor stability, with the advantages of orientation and other issues, obtained at near atomic resolution cryoelectron microscopy structure; Prior to this, the Chinese Academy of Sciences State Key Laboratory of successful development of a new type of spectrometer The instrument can be used to measure the molecular vibrational spectra, molecular orientation structure and kinetics of gas-liquid interface, gas-solid interface, supramolecular chiral interface, biofilm interface.
In conclusion, as an important part of the national science and technology innovation system, the State Key Laboratory is an important base for advanced and basic research and applied basic research and advanced scientific research and equipment of the state organization, which not only reflects the national strategic intentions but also is the main force for seizing the commanding heights of international frontiers It is especially urgent to explore and seek to establish, operate and strengthen national laboratories in the construction of key state laboratories in the current international scientific and technological achievements.
However, judging from the current construction work of key laboratories in our country, establishing an independent and impartial assessment institution, strengthening national policy funds, and conducting scientific research equipment Support and so on are still in the direction of the current construction work needs to be done.At the same time, any kind of system or mode is not permanent, for the laboratory construction methods, also need to advance with the times, avoid weaknesses, the real experiment The significance of the construction of the room to give full play to the implementation.
