　　An improved chi-squared test method used to detect frequency abnormity of atomic clock is presented.This method is independent of choice of reference value,which is applicable to the measure of data in pairs.The method may speed up the process of analysis and detection for frequency abnormity.The result shows that compared with the classical chi-squared test method,the detection performance of frequency abnormity of atomic clock are improved and the calculation procedure is simplificated.
