摘要：

材料热物性是对特定热过程进行基础研究、分析计算和工程设计的关键参数,是材料最基本的性能之一,在科学研究、工程设计、工业生产等领域应用十分广泛,也是各行业节能技术发展的基础。通过对材料热物性发展历史、国内外研究现状的分析,比较了我国与发达国家在防护热板法导热系数装置研究上的差距,阐明了热物性测试的重要意义及我国在材料热物性测试领域仍未建全量值传递体系的不足。

Abstract: Thermal physical properties of materials are the key parameters for study, analysis and engineering design of special thermal process. As the most basic characteristics of materials, thermal physical properties are widely used in scientific research, engineer design and industrial production field. They are also the basis for developing energy-saving technology in industry. In this paper, thermal properties' development history and current research progress were introduced. The difference of research on the guarded hot-plate device for thermal conductivity measurement between developed countries and China was compared. The importance of thermal properties testing was clarified. Finally, the necessity of our country to establish full value transfer system in thermal properties testing field was discussed.

Keywords: thermal physical properties of material; guarded hot plate apparatus; thermal conductivity; thermal micro-system; reference materials; value transfer system
