| 摘 要： | 对指数分布，分别在恒加应力与步加应力试验下，进行可靠性统计分析，利用高应力水平的失效数据隐含低应力水平的寿命信息，而低应力水平的失效数据无法提供高应力水平寿命信息的性质，建立必要的定量。从而得到满足顺序约束的参数估计，结论优于最大似然估计。

| Abstract: | For the occasion of exponential distribution, the reliability of accerated life test is analysed statistically under constant stress and stepwise stress respectively. Thcorems 1,2 and 3 are established by applying the property that the failure data of high stress level imply the life information of low stress level life and the failare data of low stress level are unable to provide life information of high stress level. The parameter estimate meeting sequential constraints is thus obtained, and the conclusion prevails over maximum likelihood estimate |
