| 摘 要： | 利用对数正态分布的性质，从失效概率在时间相差较小的情况下应具有时间的连续性出发，讨论了检验时刻失效概率的分层Bayes估计，进而利用分布函数曲线拟和方法得到了母体参数的线性回归估计，并结合实际问题进行了计算．

| Abstract: | Using properties of the lognormal distribution function and the failure probability with the properties of time continuity in a min time, this paper firstly discusses the failure probability of zierachical Bayesian estimator in time. And then, the linear regression estimators of the unknown parameters are given by employing the method of distribution curve fitting and the calculation of a practical problem is illustrated. |
