摘　　要：根据周期热流法测试原理,结合理论分析和实验测定,设计并开发了一套测试和计算金属及其合金高导热材料热物性参数的装置和软件。利用Visual Basic6.0的编程技术,并结合数据采集装置,实现了测试系统的数据自动采集及处理可视化功能。通过对几种金属及合金热物性参数实验测定的结果和文献值比较,发现最大误差不超过6.5%,测试结果可靠。According to the periodic heat flow measurement method, by using the method of theory analysis combined with experiment study, a set of testing system and software have been designed for measuring thermo-physical property of high thermal conductivity material. Through Visual Basic 6.0 programmed technique and data acquisition device, the visual software of data collected and disposal processing could be realized. Thermal conduetivities of several metal and alloy samples were determined, which showed that the relative errors were less than 6.5%. The testing result is credible.
