Linear expansion coefficient

Linear expansion coefficient;, Also known as linear expansion coefficient. The ratio of the change in length of a solid substance when its temperature changes by 1 degree Celsius to its length at the original temperature (not necessarily 0 ℃) is called "; Linear expansion coefficient;. Due to different substances, the coefficient of linear expansion also varies, and its value is related to the actual temperature and the reference temperature selected when determining the length 1. However, since the coefficient of linear expansion of solids does not change much, it can usually be ignored, and a is treated as a constant independent of temperature Testing advantages: 1.
