摘　　要：排序集抽样作为一种更有效的数据收集方法,近几年引起了许多学者的兴趣,特别在环境和生态的研究中已经有了不少结果。主要讨论排序集抽样在两样本刻度参数检验中的应用,并从检验的渐近效率的角度说明了基于排序集检验较一般随机抽样的优良性。Ranked set sampling has attracted considerable attention as an efficient sampling design recently, particularly for environmental and ecological studies. In this article, we consider the application of two-sample-scale tests based on ranked set sampling. And our results show that the test procedure based ranked set sampling is asymptotically at least as efficient as the random sample procedure.
