研究中国型号机械作用火工品感度分布曲线的拟合及常见类型 .应用同总体检验理论对合格的同型不同批的火工品感度数据进行综合 ,在此基础上先利用概率单位法粗估感度分布类型和分布参数 ,再利用极大似然法估计参数 ,并检验所选择的感度分布 .利用以上方法给出了中国 10种型号机械作用火工品的感度分布类型 .该分布类型中最常见的是对数 - logistic分布 ,其次为威布尔分布和
To research the fitting of sensitivity response curve for mechanism initiated pyrotechnics, the response data which came from the same type but different groups of pyrotechnics were tested and summarized by virtue of the testing theory of the same ensemble. Based on the data, probability unit method was used to estimate the type of response curve roughly. Furthermore, the maximum likelihood estimation of parameters and χ 2 test for model were discussed. The fitting method was applied to ten kinds of mechanical initiated pyrotechnics. The ln logistic distribution is the most common type of distributions for mechanical initiated pyrotechnics.
