May 20th is World Metrology Day. As the country's highest metrology scientific research center, the Chinese Academy of Metrology has achieved a number of scientific and technological achievements that the country urgently needs in recent years. In terms of cutting-edge research in metrology technology and measurement capabilities that serve the country's economic and social development, etc. It has developed and entered the forefront of world metrological research.
During the "Eleventh Five-Year Plan" period, the Chinese Academy of Metrology launched pre-research on key technologies and value transfer systems in six new measurement areas, including new energy, new materials and nanotechnology, biosafety, environmental measurement, medical measurement and instrumentation . Among them, two projects of new materials and nanometering and medical metering have been approved by experts as the "12th Five-Year Plan" national science and technology support plan project.
In accordance with the needs of national economic and social development, the Chinese Academy of Metrology has made significant progress in aerospace engineering, Beijing Olympics, Three Gorges Project, West-East Gas Transmission, energy conservation and emission reduction , food safety, medical care and forensic science.
The cesium atomic time-frequency reference clock independently developed by the Chinese Academy of Metrology provides services for Beidou satellite navigation and positioning system; the established high-precision laser two-coordinate standard device breaks the core component required by the integrated circuit and liquid crystal display manufacturing industry—mask The traceability of the value of the board has relied on the situation of developed countries for a long time, which has solved industry problems and filled domestic gaps.
At the same time, the ventilator and infusion pump measurement calibration standards and traceability system established by the Chinese Academy of Metrology have made contributions to the service of influenza A prevention and control; researched and established large-scale water flow measurement and Three Gorges flow measurement standard devices have solved The ultrasonic flowmeter of the Three Gorges Power Station accurately assesses the problem of large-caliber water flow and provides technical support for evaluating the power generation efficiency of the Three Gorges Power Station. The study of standard substances forbidden substances in forensic science provides technical support for accurate judgments in the judicial field.
In order to cope with major changes in the international unit system and improve national competitiveness, the Chinese Academy of Metrology also launched a "new-generation metrology-based standards research based on quantum physics". These major frontier projects in metrology include 10 basic, forward-looking and Innovative topics. These topics are technically difficult and high-level, such as strontium atomic clocks, power balances, optical radiation quantum standards, etc. The research of the Chinese Academy of Metrology has achieved major technological breakthroughs and stage results.
