导热系数就是物体中温度降度为 1℃时，单位时间内通过单位面积的导热量，

Thermal conductivity is the amount of heat passing through a unit area per unit time when the temperature drop in the object is 1 ° C. Its unit is W / m · k. The numerical value of the thermal conductivity expresses the magnitude of the material's thermal conductivity. The thermal conductivity values ​​of various materials used in engineering calculations are generally determined by experiments. Thermal conductivity is generally related to the density, temperature, humidity and heat flow direction of the material.

The thermal coefficient is the temperature drop in an object of 1 oC, the unit time through the unit area of the heat, its unit is W/m.k. The value of thermal conductivity indicates the size of the material's thermal conductivity. The thermal conductivity values of various substances used in engineering calculations are generally determined by experiments. The thermal conductivity is generally related to the density, temperature, humidity and direction of the heat flow of the material.
