摘　　要：本文主要介绍临床试验中的等效性检验的概念、原理、作用以及成组设计一元定量资料等效性检验的SAS实现。基于原始的定量数据或者基于给定样本含量、均值、标准差两种数据结构,结合实例展示SAS在等效性检验中的应用,并对结果进行解释、做出结论。This article mainly introduced the concept,principle and function of equivalence test in clinical trials and the implementation of SAS for equivalence test of unary quantitative data in group design.The application of SAS software in the equivalence test was demonstrated through examples.The operation was based on the original quantitative data or the data structure of the given sample size,mean and standard deviation.And it was also to explain the results and make the conclusion.
