Temperature, as a fundamental physical quantity closely related to our lives and production, has indisputable importance in measurement. In the vast field of scientific exploration, whether in microscopic quantum experiments or macroscopic astrophysical research, temperature measurement holds a crucial position. In chemical experiments, precise temperature control is the key to synthesizing complex compounds. A slight temperature deviation may lead to completely different reaction results and products. For example, in polymerization reactions, temperature significantly affects the molecular weight and properties of polymers. In physical experiments, researching the characteristics of superconducting materials at low temperatures and the thermal expansion coefficient of materials requires high-precision temperature measurement to obtain accurate data.
In industrial production, temperature measurement is a core link in ensuring product quality and production safety. In the steel smelting process, from the smelting of iron ore to the forging of steel, each stage has specific temperature requirements. Accurate temperature measurement can ensure that the hardness, toughness and other properties of steel meet the standards. Electronic component manufacturing is even more temperature-sensitive. In the chip manufacturing process, steps such as lithography and doping need to be carried out in a constant temperature environment. A slight fluctuation in temperature may cause defects in chips and affect their performance and reliability.
In daily life, temperature measurement is also everywhere. From the weather forecast we are familiar with, behind it is the precise measurement of air temperature, ground temperature, etc. by a large number of meteorological stations. To household appliances such as air conditioners and refrigerators, temperature sensors are used to achieve temperature regulation and create a comfortable living environment for us. In the medical field, the measurement of human body temperature is an important basis for diagnosing diseases. From ordinary fevers to the early screening of some serious diseases, temperature measurement plays an irreplaceable role. Therefore, temperature measurement runs through all aspects of our lives and production and is an important guarantee for the normal operation of modern society.
