摘　　要：平均间隙法(Hannover-法)是监测网基准点稳定性检验的主要方法,包括整体检验和局部检验两大步骤。针对实际应用中如何构造假设检验的统计量、自由度的计算和F分布表的取值问题,通过两种不同思路从理论上进行推导,给出正确的计算公式,并证明两种思路的一致性,最后以实际算例进行了验证。Hannover-method is a popular method to test the stability of monitoring benchmarks which includes two steps：the whole test and the local test.In practice,different books have different results about how to build up the statistical models and calculate the freedom degrees for the hypothesis test.This paper focused on the theoretical deduction of stability test models from two different aspects and gave the correct formulas.The consistency of two methods was approved by both theoretical deduction and practical application.
