摘　　要：讨论双参数指数型分布最小和最大次序统计量矩的计算,利用双参数指数型分布矩的递推关系及密度函数的特点获得了它的最小和最大次序统计量各阶矩以及各阶混合矩的精确计算公式.The calculation of the minimum and maximum order statistic moments of two-parameter exponential distribution was discussed. The moments and mixed moments precise calculation formula of twoparameter exponential distribution were obtained by using the recursive relations of moments and the characteristics of the density function of two-parameter exponential distribution.
