摘要
本文讨论了关于寿命试验的一些问题，全文共分四个部分．第一部分分析了截断情况下寿命估计的困难；第二部分考虑对定时寿命试验方法进行修改，以获取分布尾部的信息；第三部分研究在随机截断下基于Ｋａｐｌａｎ－Ｍｅｉｅｒ估计的非参数寿命均值估计；第四部分讨论了第二类截断下定数ｒ的选择问题．
We discuss the problems about lifetime testing in this paper by four parts. In the first part we point out the difficulties that we may meet in the lifetime testing. In the second part the estimations of the lifetime in non-parametric model under nodified type Ⅰ censoring are considered while the estimations of mean lifetime under random censorship model are given based on the Kaplan-Meier estimator in the third part. In the last part we study how to determine the r value of the type Ⅱ censoring to save the money and the time.
