摘　　要：本文讨论了分层抽样问题中各总体均值线性组合的估计误差及其T型统计量分布的随机加权逼近的收敛速度,在一定的条件下证明了其速度可达(?),其中n为样本总容量。In this paper, we investigate the convergence rate of the random weighting approximalon of the distributions for the estimation error and the student's statistic of linear combination of the means in stratified sampling. Under some conditions, we haveproved that the rate can reach .
