中文摘要：

构造混合指数族分布,分别在正常工作条件下和恒加应力加速寿命试验条件下的完全数据场合、定时截尾和定数截尾的情形下,利用EM算法估计混合指数族分布的参数,综合文献进而得到更一般的结论.最后通过模拟,讨论了一种特殊的混合指数族分布的参数估计问题.

英文摘要：

This paper firstly constructs a mixed exponential family distribution.Secondly,we employ the EMal-gorithm for the mixed exponential family distribution model under the normal stress life time test with full data or censored samples.Comprehensive literature then helps us get more general conclusions.Finally,the paper dis-cusses a special mixed exponential family distribution parameters estimation through simulation.
