Therefrom , this thesis puts forward the shock model with seven individually independent sources and structure three - dimensional exponential distribution , which its edge distribution is only bivariate distribution of marshall - olkin
由此，本文提出七个相互独立冲击源的冲击模型，构造了三维指数分布，并且它的二维边缘分布恰是marshall - olkin二维指数分布。
Exponential distribution is the most important distribution in relia - bility theory . in reliability history . famous marshall - olkin applied the fatal shock model with three mutually independent shock sources to build bivariate exponential distribution
在可靠性数学理论中，指数分布是一类很重要的分布。可靠性历史上著名的marshall - olkin ，利用三个相互独立冲击源的致命冲击模型，建立了二维指数分布。
