平面热源法瞬态测量材料热物性的研究

Investigation of Transient Measurement Thermal Physics Properties by Plain Thermal Source Method

简述了平面热源法瞬态测量材料热物理性质的基本原理,分析了快速法、脉冲法测量存在的问题。在此基础上,研究了材料热物性瞬态自动测量技术。测量实践表明:瞬态自动测量仪测量准确可靠,与用防护热板法测量的结果也符合得很好。

At present paper, we recite the basic principle of plane hot fountain to measure the heat physical property instantly and analysis the problem between the instant measurement and pulse measurement. basic on this, We study the instant automatic measurement technology of the heat physical property. Our practice indicated that instant automatic measurement is exact and credible, accord with the result of plane heat measurment well.
