Role and significance:
1, measurement and science and technology
As we all know, science and technology is an important basis for human survival and development. Without science and technology, there can be no human 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 law of things; and all things are composed of a certain amount of "quantity", and through the "quantity" to reflect. In order to recognize the quantity and obtain its value exactly, only through measurement.
2, measurement and production
Measurement of the role and significance of industrial production is very obvious. Socialized mass production itself requires a high degree of measurement to ensure. The development of production can be roughly divided into three stages, namely, experience-based stage, semi-empirical, semi-scientific stage and scientific stage.
Measurement is the technical basis of scientific production. From the screening of raw materials to the quota feeding, from the process monitoring to the product quality inspection, are inseparable from the measurement.
3, measurement and people's lives
Measurement of the significance of people's lives is quite obvious. The measurement of the production process can not be ignored, the measurement of life should be more concerned. It directly touches people's personal interests, and sometimes very sensitive.
4, measurement and trade
Measurement and domestic trade, has been slightly involved in the previous and generally also have a feeling; the following will only talk about measurement and international trade.
5, measurement and national defense
Measurement of national defense, especially the importance of cutting-edge technology, especially prominent. National defense cutting-edge system is huge and complex, involving a wide range of scientific and technological fields, high technical difficulties, requiring measurement of many parameters, high precision, large range, wide bandwidth.
Extended information:
Measurement is the use of technology and legal means to achieve the unity of the unit and the value of accurate and reliable measurement. In the measurement process, the use of gauges and instruments are considered to be standardized, and they are used to calibrate and calibrate the inspected gauges and instrumentation, in order to measure and ensure the reliability of the measurement results obtained when using the inspected gauges and instruments to make measurements.
Measurement involves the definition and conversion of units of measurement; the transfer of quantitative values and to ensure the unity of quantitative value of the measures that must be taken, regulations and legal system.
Transmission and tracking of measurement values
Transmission and tracking of measurement values is a physical unit of measurement through the various levels of benchmarks, standards and the corresponding auxiliary means of accurately transferring to the daily work of the measuring instruments used in the measuring instruments, in order to ensure the unity of value of the whole process.
Measuring instruments
Reproducing the quantitative value or measured into directly observable indicator value or equivalent information gauge, instrument, device.
Measurement standards
Accuracy lower than the measurement reference, used to test the measurement standard or the work of measuring instruments of measuring instruments. It can be classified according to its accuracy level, such as level 1, level 2, level 3, level 4, level 5 standard weights. Standard apparatus according to its legal status can be divided into three categories:
(1) the social public standard of measurement refers to the measurement of the local government departments above the county established as a unified basis for the value of the region, and the implementation of the measurement of the community to supervise the notarial role of the measurement of various standards.
(2) departmental use of measurement standards is the competent government departments at the provincial level or above to organize the establishment of a unified basis for the measurement of the value of the department's measurement standards.
(3) enterprises and institutions to use the measurement of standards is the enterprise, the organization of institutions as the unit based on the measurement of standards.
