| 摘 要： | 以消除年变化等短周期变化后的数据做为当月正常值，利用实测的月均值与正常值之比即月干扰比率、偏差等指标，突出反映月观测值在当月受到综合干扰因素影响的大小。从而突出地震前短临地电阻率异常。

| Abstract: | In this article, an attempt is made to eliminate short-period change from data, and then take it as the normal data for that month, finally calculate the monthly interference ratio as the ratio of the average data of each month and the normal data, and calculate the deviation to reflect the size of the impact by the comprehensive interference. In this way, we highlight the abnormal performance of the resistivity before the earthquake. |
