Abstract: The Theoretic basics of ARGT were founded.They include the defination of A f(Acceleration Factor)for ARGT and its properties were given,the essential relations between these properties and the condition having same failure mechanisms at the normal and accelerated stress levels were presented.These results are applied to the common reliability growth modets.And the fundamental hypotheses of statistical analysis for ARGT were proposed.

摘要： 建立了加速可靠性增长试验 (ARGT)的理论基础 ,包括给出ARGT的加速系数 (Af)的定义与性质 ,这些性质与正常加速应力条件下有相同故障机理条件间的本质联系 ,并将这些结果用于常见的可靠性增长模型。最后提出了作ARGT统计分析所依据的基本假定。
