Abstract: Developed countries in the America and Europe attach great importance to the development of metrology and measurement technology,incorporating forward-looking and fundamental measurement technologies such as quantum and digital intelligence into their national development strategies,and seizing the technological high ground.In recent years,China has made breakthroughs in metrology research fields such as atomic frequency standards and cold atomic gravimeters,and has entered the ranks of advanced countries in international metrology.At present,with the quantization and digital transformation of international metrology,the evolution of quantization in metrology is constantly accelerating,the mode of measurement transmission is gradually transitioning towards digitization,and the trend of metrology support technology is becoming more practical.The development trend of metrology and measurement technology is given and a close analysis is made in this paper,providing a useful reference for the development of China metrology and measurement.
