文章以巷道检验为例,根据试验中的变差来源,论证了样本容量n=6时,升降法在敏感度试验特别是在巷道检验中应用是完全可行的,并提出确定试验参数的原则.%In this paper, according to the source of variation based on tunnel tests, the application of up-and-down method in the experiment to test sensitivity, especially in tunnel tests, is discussed as the sample size is 6. The results in-dicat that this method is available, and the principle to identify the parameters of experiment is also given at the end.
