摘　　要：设系统由两个部件组成,两个部件的寿命均服从指数分布.本文利用样本空间排序 法,针对各部件获得定总时有替换为寿命试验数据,给出了系统可靠度的精确置信下限及其有效的 计算方法.This paper deals with any system with two components. The lifetime of each component is distributed as exponential distribution. Based on the data obtained from the tests with fixed total time and replacement for the components, the lower confidence limits of reliability for the system are found. We present not only a strict theory but also an efficient computational method.
