摘　　要：改进了传统火工品感度分布的5种分布的拟合方法,完整地给出了Box-Cox正态分布及其分布拟合方法,并在Pearson χ2距离的意义下,用15种火工品实例验证了Box-Cox正态分布拟合大部分优于传统的5种分布拟合。The traditional goodness-of-fit approaches for five sensitivity response curves of pyrotechnics were improved, and the Box-Cox normal distribution and its goodness-of-fit approach were entirely given. Under the Pearson X^2-distance, it is shown that the goodness-of-fit using Box-Cox normal dis- tribution is more superior than that using traditional five distributions in most cases of the 15 examples.
