摘　　要：依托阿伦纽斯公式进行等效老化,可以作为工程上加速老化的理论基础,并应用到下面场景:在给定试验温度和试验周期的情况下,计算实际(或预期)工作环境温度下的寿命;估计已知的历史环境温度和保守的预期未来环境温度下的剩余寿命。分析了阿伦纽斯热老化模型有前提条件、敏感性和局限性,对其可能的局限性以及修正方案给出了说明。通过研究阿伦纽斯公式,将其应用在核电厂电仪设备时限老化分析中的热老化分析,并给出比10℃经验方法更科学的论证。The equivalent aging based on Arrhenius formula can be used as the theoretical basis of accelerated aging in engineering.It is applied into the following scenarios:under the given test temperature and test cycle,the life is calculated under the actual(or expected)working ambient temperature;the remaining life is estimated at known historical ambient temperature and conservative expected future ambient temperature.The preconditions,sensitivity and limitations of Arrhenius thermal aging model are analyzed,and its possible limitations and correction scheme are explained.Through the research of Arrhenius formula,it is applied to the thermal aging analysis of Time-Limited Aging Analysis for electrical instruments and equipment in nuclear power plant,and a more scientific demonstration is given than the empirical method of 10℃.
