摘　　要：物质热稳定性是危险化学品生产、储存、运输和使用中最为关心的问题之一,热稳定性实验方法和仪器是获得物质热稳定性特征参数的重要技术和手段。本文介绍了国际上分析物质热稳定性的几种主要实验方法的测量原理,所用量热仪的结构、工作原理、热探测灵敏度、测试条件、范围及所获得的典型数据。综合比较了各种量热仪的性能,应用条件及其适用范围和优缺点。Thermal stability of reactive materials （TSRM） is one of the most important qualities of hazardous chemicals in their production, storage, transportation and application. This paper introduces the priniciples for testing TSRM and describes the constructions, working principles, thermal sensitivities and pressure and temperature ranges of the thermal analysis instruments and the typical data that can be obtained. The performances, operational conditions, application fields and merits and shortcomings of various thermal analysis instruments are compared.
