摘要
关于指数样本中下异常值的检验，各种文献中仅对下异常值个数已知的情况作了讨论．当下异常值个数未知时，因存在ｍａｓｋｉｎｇ或ｓｗａｍｐｉｎｇ效应，检验问题变得十分复杂和困难．本文成功地解决了这一问题．
\ \ For the test of lower outliers in a exponential sample,most literature only dealt with the case in which the numble of outlier are known.When the numble of outliers are unknown,the problem becomes very complicated because of masking or swamping effet.In the paper,The authors solve the problem.
