Just as the slogan of the Olympic Movement is "Higher, Faster and Stronger", the pursuit of instrument science and technology in improving the scientific research level and the technical indicators and functions of related instruments is endless. The technical index of measurement and control technology and related instruments is a quantitative standard of national instrument science and technology. In terms of indicators, the detection range is expanded, such as the voltage from nanovolt to millivolt; Resistance from superconductivity to 10 14ω meridian; Harmonic measurement to 5 1 time; The acceleration is10-14 ~104g; The measured frequency is1012hz; The pressure is measured to 108Pa, the temperature is measured to 1080C and so on. In terms of measurement accuracy index, industrial parameter measurement has been improved to more than 0.02%, and aerospace parameter measurement has been improved to more than 0.05%. The measurement accuracy and the accuracy achieved by scientific instruments have kept pace with the times. In order to improve the sensitivity of measurement, it is developing to the level of single particle, molecule and atom. Improve the measurement speed (response speed), static 0. 1~0.02ms, dynamic 1us. To improve the reliability, the general requirement is (2~5)× 104h, and the high reliability requirement is 2.5× 105h. Stability (annual change)? 0.05% (high precision instrument) or? 0. 1% (general instrument). Improve the environmental adaptability of products. According to the requirements of different users, there are conditions such as high temperature, high humidity, high dust, corrosion, vibration, impact, electromagnetic field, radiation, deep water, rain, high voltage electricity and low voltage.
