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。

By comparison between SMM HXRBS observation and ground observation of Hα and CaIIK lines, especially through the combined study between SMM HXRBS observation and chromospheric flare models, the results show that: in the initial stage of impulsive phase, there is a correlative relation betweem Hα line intensity and hard X-ray emission; different spike in hard X-ray flux curve represents the burst at different location; the energy taken by non-thermal electron beam is larger than the radiative loss in chromosphere; for the flare studied here, the chromospheric evapporation is explosive; if the chromosphere is in balance between electron beam bombardment and radiative loss, the column mass density at the top of chromospheric flare model can not be taken as measure from the source of electrons and then the total material between the source of electrons and the top of chromosphere can be estimated.
通过一个具体耀斑的SMM HXRBS观测结果与同时基于地面得到的Hα和CaⅡK可见光谱观测结果对比,特别是将硬x谱观测结果与色球半经验模型联立研究,结果显示出:在脉冲相上升段,硬x发射与Hα辐射之间存在对应关系;硬x线光变曲线中不同脉冲爆发分量不太可能起源于同一位置;硬x辐射所反映的高能非热电子总携带能量大于色球总辐射损失;对所研究的耀斑而言,其色球蒸发过程是爆发性的;在详细比较了非热电子色球总沉积和色球辐射损失的基础上,指出半经验模型中色球顶部柱数密度不能看成是从非热电子源度量的,从而估计了色球顶部到非热电子源之间的总物质。
