摘要
建立起热脉冲法的新理论模型,分析了相应的测试技术问题。利用研制的微机测试系统对几种材料的热扩散系数和导热系数进行了测定,得到了满意的结果。
A new physical and mathematical model of the thermal impulse method is set up.The testing techniques are discussed and analysed.The thermal conductivities and diffusivities of several materials are measured with the microcomputer measuring device designed and satisfying results are obtained,that the measuring method reported in this paper is simple and reliable.
