摘　　要：对长期贮存一次使用的设备元器件采用性能退化方法评定其可靠性,该方法大多采用对各时刻的测量数据进行统计分析得出相应的可靠度再拟合出可靠度函数,给出了一种利用规则性能退化数据结合幂律退化轨道的可靠性评定新方法。For long-term storage of one-shot equipment components, performance degradation method was used to evaluate its reliability. This method mostly statistically analyzes each moment measuring data to get the reliability and then fits the reliability function. This paper gives a new reliability evaluation method which uses regular per- formance degradation data and combines power-law degradation path.

关 键 词：性能退化数据 幂律退化轨道 性能参数 性能可靠度 失效阈值
