In May 20th this year, it was the nineteenth world measurement day. The State Administration of supervision and administration, the China Science and Technology Association and the Central Committee of the Communist Youth League held the 2018 World metrology day in 2018. Zhang Mao, director general of the State Administration of market supervision and management, said in his keynote speech that after years of efforts, our country's ability to obtain international recognition of calibration and measurement has leaped into the world's fourth, the first in Asia, and made important contributions to the redefinition of international units such as length, temperature and electricity.
The theme of this year's world metrology day is "the quantized evolution of the international system of units". Zhang Mao said that the quantized evolution of the international system of units is another major change in the use of natural law to create measurement rules. The new international measurement unit system can make the measurement datum come back anytime and anywhere, and apply the most quasi "scale" directly to the production and life. This will promote the reform and innovation of the measurement management model which is the main body of the physical measurement instruments. The new State Administration of market supervision and administration should seize the major opportunities for international measurement reform, actively plan and promote scientific and technological innovation in the field of global vision, promote the national core competitiveness, and provide powerful measurement technical support and guarantee for building a powerful country and a quality power.
According to the introduction, in order to disseminated and popularize the knowledge of measurement and improve the level of scientific quality of the whole people, the Chinese Science Association, the State Administration of market supervision and the Central Committee of the Communist Youth League have carried out the collection of creative and creative materials for the National Metrology science and technology.
