<正>本文用非参数统计法,分析了两类船闸系统的可靠度。给出了x~2和N(0,1)分布计算可靠度单侧置信下限R的近似公式。

In this paper, the reliability of two types of lock gate system is analysed with nonparametric statistics. An approximate formula to calculate the one-side fiducoal lower limit R of the reliability with x2 and N(0, 1) distribution is presented, the real example analysis has been made with this result, and the fine effect obtaine.
