对基于Arrhenius模型、Norris-Landzberg模型和Peck模型等模型的加速寿命试验理论进行了简要阐述，针对空间应用系统空间电子学设备可靠性特点和加速寿命试验难点，提出了一种基于性能退化模型的电子学整机系统加速应力试验方法，最后给出了实例，为减少试验设计中的不确定性因素提供了一种新的思路。%The accelerated life test theories based on Arrhenius , Norris-Landzberg and Peck models were briefly introduced .Targeting the reliability features and the difficulties of accelerated life tests , an accelerated stress test method for space-electronic equipments was proposed based on a perform-ance degradation model .In the end , application examples were given to verify the proposed method . This provides a brand new idea for the reduction of uncertainties in the test design stage .
