Abstract : the sequentially censored statistical testing scheme of success ratio , of which the deducing process is based on probability ratio or likelihood ratio , is commonly used in reliability demonstration test 摘要：成功率序贯截尾统计试验方案是可靠性验证试验中的一种常用方案，其理论推导过程基于“概率比”或“似然比” 。
The recursive modification algorithm is mainly based on the ideal of stochastic approximation and truncation technique to obtain modification strategy for estimated parameters , it is proved that these modification parameters turn out to be a constant vector 其中迭代的参数修正策略主要是基于随机逼近思想和截尾技术给出了修正向量的构造算法。
In this paper , we study the type - i life test of lognormal , normal and weibull distributions with large numbers of samples , get the approximate confidence regions of the parameters , and do many stochastic simulations on the theoretical basis with computer 本文研究了大样本定时截尾寿命试验下对数正态分布、正态分布和weibull分布参数的近似置信域，并在理论基础上进行随机模拟。
Abstract : in this paper , we obtain the point estimetions and the approximate confidence interval of the environment factor of the lognormal distribution based on the censoring samples . the accuracy of the approximate confidence interval is studied by the simalation method 文摘:本文导出了寿命分布为对数正态分布时基于截尾样本环境因子的点估计和近似置信限，对所给近似置信区间作了模拟研究。
A class of strong convergence theorem for an arbitrarily adapted stochastic sequence without the non - decrease condition was established by using the truncation method of stochastic variables and the stop time 摘要引入了随机变量的截尾和停时的概念，在定理条件及其证明过程中适当地定义随机变量的截尾和停时，并通过定义鞅差序列和利用鞅差序列的收敛定理，得到了一类关于任意随机适应序列的强收敛定理。
Present to use sequential posterior odd test , which can be abbreviated spot , to verify reliability and maintainability index , and give the methods respectively of based on simple hypothesis , complicated hypothesis and censoring spot method under the ground of known two class risks 提出利用序贯验后加权检验( sequentialposterioroddtest ,简称spot )方法对r & m指标进行验证,在两类风险已知的条件下,给出基于简单假设、复杂假设和截尾情况下的spot方法。
