什么是导热系数？

Answer: The thermal conductivity, also known as heat conductivity, refers to the amount of heat transferred through a 1-meter-thick material in a stable heat transfer condition, with a temperature difference of 1 degree (K, ℃) between the two surfaces within 1 second (1s), and across an area of 1 square meter. The unit is watts per meter degree (W/(m·K)). Thermal conductivity is an important indicator for measuring the heat conduction performance of a material. The higher the thermal conductivity, the faster the material conducts heat.
