摘　　要：在有替换定数截尾寿命试验样本下,将Bayes方法与矩估计法相结合,对不可修k/N(G)系统可靠性指标的估计问题进行研究,获得了组成部件的失效率、系统可靠度和平均寿命的经验Bayes估计.最后利用随机模拟的例子说明了所给方法是有效的.Based on the samples＇ type Ⅱ-censoring life test with replacement, the problem of estimating the reliability performances for Non-repairable k/N（G） system were studied by using Bayes and moment estimation. While the failure rate of component part was obtained, the reliability function of the system and empirical Bayes estimation of mean lifetime were also achieved. Eventually, the accuracy of the method was proved by a random simulating example.
