摘　　要：利用分布密度分拆的思想,导出了二元及多元Freund型指数分布的一个特征,利用该特征,获得了二元及多元Freund型指数分布参数的最大似然估计及矩估计,还给出了强度服从二元Fre-und型指数分布时并联结构系统的可靠度估计及模拟.Based on partitioning technique of distribution density, a characteristic of the multivariate exponential distribution of Freund is derived. Using the characteristic found, the maximum likelihood estimators and the moment estimators of parameters of the multivariate exponential distribution of Freund are obtained. In addition, the estimator of reliability is given for parallel structural system with strength showing the bi-variate exponential Freund distribution, and finally some relevant simulation results are presented.
