Abstract：Applied runs test method of statistical analysis theory, air gap value measured actually is made statistical test and decided on random variable, and its eigenvalue is gained. Further using the F-test and t-test, the air gap value’s mean value and variation of variance are deduced and, the confidence interval of air gap before and after the heavy repair is decided. In accordance with the statistical test result , the paper expatiated the actual meaning of the statistical analysis result , brought forward a criterion and a view which are different from the form gotten with conventional methods , for dealing with the air gap value adjust measured actually and the air gap abnormal value.
