摘　　要：文章介绍和分析了温度试验中的试验箱温度稳定和试件温度稳定的定义,民用标准和军用标准有关试件温度稳定的定义及其区别,温度稳定时间的确定方法,特别是确定试件温度稳定的三种方法及其优缺点和应用情况;介绍了保温时间的概念及其在高低温工作试验中的组成,分析了各组成部分的含义以及GJB 150和MIL-STD-810两个系列标准中这一组成部分的变化情况;最后提出了确定受试产品温度稳定时间一些建议。The definitions of both the chamber temperature stabilization and the test sample temperature stabilization in temperature tests are introduced. The definitions of the test sample temperature stabilization in civilian and military standards and their differences are analyzed. The methods for determining the temperature stabilization time are discussed, especially, the pros and cons of three commonly-used methods and their applications. The concept of the temperature maintaining time and its composition in high and low temperature operation tests are introduced. The related specifications in GJB 150 and MIL-STD-810 serial standards are discussed. Finally, some suggestions are made to determine the test sample＇s temperature stabilization time.
