1, metrology and science and technology

As we all know, science and technology is an important foundation for human survival and development. Without science and technology, there would be no human beings today. In fact, measurement itself is an important part of science and technology.

Any science and technology is to explore, analyze, study, master and use the objective laws of things; And everything is composed of a certain amount, which is reflected by it. In order to know this quantity and get its value accurately, only through measurement.

2, measurement and production

The function and significance of measurement to industrial production are obvious. Socialized mass production itself needs a high degree of measurement guarantee. The development of production can be roughly divided into three stages, namely, empirical stage, semi-empirical stage, semi-scientific stage and scientific stage.

Measurement is the technical basis of scientific production. From the screening of raw materials to fixed feeding, from process monitoring to product quality inspection, it is inseparable from measurement.

3. Measurement and people's lives

The significance of measurement to people's lives is quite obvious. The measurement of production process can not be ignored, and the measurement of life should be paid more attention to. It directly touches people's vital interests and is sometimes very sensitive.

4, measurement and trade

Measurement and domestic trade are slightly involved, which is generally felt; Let's just talk about measurement and international trade.

5, measurement and national defense

Measurement is particularly important to national defense, especially cutting-edge technology. The sophisticated national defense system is huge and complex, involving a wide range of scientific and technological fields and high technical difficulty. It requires many parameters, high precision, large measuring range and wide frequency band.

Extended data:

Metrology is a measurement that uses technical and legal means to achieve unit unity and accurate and reliable value. In the process of measurement, it is considered that the measuring tools and instruments used are standard and used to calibrate and verify the measured tools and instruments, so as to measure and ensure the reliability of the measurement results obtained when using the measured tools and instruments.

Measurement involves the definition and transformation of measurement units; Measures, regulations and legal systems that must be taken to convey and ensure the unity of values.

Transmission and tracking of magnitude

The transmission and tracking of values is the whole process of accurately transmitting a physical quantity unit to measuring instruments and measuring tools used in daily work through benchmarks, standards and corresponding auxiliary means at all levels to ensure the unity of values.

measuring instrument

Measuring tools, instruments and devices can reproduce numerical values or be measured and converted into directly observable indicating values or equivalent information.

Standard measuring instrument

Measuring instruments with accuracy lower than the measurement standards are used to verify the measurement standards or working measuring instruments. It can be classified according to its accuracy grade, such as 1, 2, 3, 4 and 5 standard weights. Standard bills can be divided into three categories according to their legal status:

(1) The social public measurement standard refers to the measurement standard established by the measurement department of the local government at or above the county level. As the basis for unifying the value of the local area, it plays a notarization role in the measurement supervision of the society.

(2) The measurement standard used by the department is the measurement standard that is established by the relevant competent departments of the government at or above the provincial level to unify the value basis of the department.

(3) The measurement standards used by enterprises and institutions are the measurement standards established by enterprises and institutions as their own value basis.
