查询词典 semi-diesel

At the beginning, an engineering method called semi-empirical reliability estimation method is introduced. Then, a detailed introduction of the bootstrap method, which has been widely applied to small sample reliability assessing since it was proposed in 1979, is made immediately. At last, a promoted virtual sample expanding method, that the reliability test sample size is expanded from 2-3 to 10, is proposed on the basis of predecessors research results. And the new method associated with bootstrap method is used to assess the test life lower limit in the case of logarithmic normal distribution.

首先阐述了处理极小子样可靠性评估问题较合理的一种工程处理方法—半经验可靠性评估方法，随后详细介绍了近年来在小子样可靠性评估领域发展迅速的Bootstrap方法，最后在前人研究成果的基础上提出了将样本数从n=2～3虚拟增广至n=10的虚拟增广样本推广方法，将该方法应用于服从对数正态分布的寿命总体，利用Bootstrap方法得到了试验寿命下限的估计，并与已有的半经验可靠性评估方法的结果作了比较分析。
