摘要
给出了一个新的概率分布,其分布函数为其中t_0=θ~β,称它为Z分布函数。并研究了Z分布的性质。如果用这种分布函数去研究炮弹贮存寿命或其它产品的寿命比用其它分布的结果要好。
A new probability distribution called Z ?distribution function is givenwhere t0=θβ and its properties are studied . For investigating the store life of cannon-balls and the life of some other products it is found that the result by using this distribution function is better than results by using other distribution functions .
