导热系数测试方法的综述

摘要

本文介绍了导热系数的五种测试方法，描述各种方法的测试原理及其计算方法。材料导热系数测试方法各有其特点，在选择时。应该充分考虑测试材料的性质、导热系数范围、测试温度等。%The paper introduced five test methods of thermal conductivity, and described principles and computational methods of the five methods. Different test methods have their own feature. When we chose one of them to test the material, we should take characteristic of material, range of thermal conductivity value and test temperature into account.
