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 logistic分布 To study the fitting and common types of sensitivity distribution curve of mechanical products in China, the sensitivities of different types of pyrotechnic products of the same type and the same type were combined with the general test theory, and then the sensitivity distribution Type and distribution parameters, and then use the maximum likelihood method to estimate the parameters, and test the selected sensitivity distribution.Using the above method is given the sensitivity of 10 types of mechanical products in China inductive distribution of the type of distribution of the most common type Log-logistic distribution, followed by Weibull distribution and logistic distribution
