摘　　要：对于失效时间遵从指数分布,本文提出了定时截尾样本下可靠性抽样检验方案的统计方法.质量统计是不可靠度的矩估计的严格增加函数,利用渐近正态分布样本量和接受常数被近似确定.This paper proposes a statistical method of working out reliability sampling inspection plans under Type Ⅱ censored sample , respectively, for items whose failure times are distributed as Exponential distributions. The quality statistic is a monotonous function of a method of moments estimator of the unreliability. An approach of choosing a truncation quatity are advanced . The acceptability constant and the sample size are approximately determined by using Normal distribution.
