In this paper,the sequential estimation of the parameter of normal distribution is studied.At first,the Bayes double sampling sequential estimation method is constructed.And then,as the requirment for testing analysis,the recursive algorithm of the estimator of distribution parameter is given.Thus,it can easily be realized in engineering applications. 论述正态总体分布参数的序贯估计和Bayes序贯估计问题。在Stein的双子样序贯估计的基础上 ,构造了Bayes双子样序贯估计 ,并作了剖析。此外 ,为了适应当前试验场地“试试看看 ,看看试试”的试验分析和鉴定的需要 ,给出了以序贯Bayes检验为基本出发点 ,使检验和序贯估计相联合的分析方法 This paper discusses Bayes sequential estimation of normal distribution parameters in multi-stage testing. An estimation scheme is given and is extended to multi-stage circumstances. Problems in engineering applications are analyzed and solutions are proposed. 讨论在多阶段试验下正态分布参数的Bayes序贯估计,给出了估计方案,并扩充至多维的场合。对工程应用中的一些问题作了思考,提出了处置方法。 In this paper,the Bayesian sequential estimation of the parameter about acceptance test of products is studied.Based on sequential test,we confine the parameter in a smaller and more precise domain.After that,Bayesian method is applied in this domain to get the Bayes estimation of the parameter θ. 论述了产品验收试验中参数θ的Bayes序贯估计。首先基于序贯检验确定了θ的较小的范围,在这个范围内运用Bayes方法求θ的估计。
