An index distribution is a distributing function which can describe the life-span of some electronic elements well. 指数分布是一种可以很好地描述某些电子元件的寿命的分布函数。
Sample space order method is used to give the lower confident limits of mean life under unequal time truncations for exponent distribution. 使用样本空间排序法给出了指数分布情形下不相同定时截尾试验平均寿命置信下限的估计方法。
