摘要
阿伦尼斯(Arrhenius)加速因子常用于可靠性加速寿命试验(ALT)或环境应力筛选(ESS)的温度应力加速寿命模型中,但事实上Arrhenius方程和由其得出的Arrhenius加速因子之间存在着矛盾。本文首先提出这一矛盾,接着从激活能的定义及物理意义进行分析,说明了引起矛盾的原因,并最终得出修正Arrhenius加速因子。
The Arrhenius acceleration factor is usually used to acceleration life model for analysis of acceleration life test and environmental stress screening data, but there is a contradiction between Arrhenius equation and acceleration factor which is resulted from the equation. Firstly, the contradiction is introduced, then the definition and physical meaning of active energy are analyzed and the reason for the contradiction is explained,at last the the Arrhenius acceleration factor is modified.
