| 摘 要： | 本文研究了从复杂地电阻率变化背景上提取地电阻率临震突变信息的数学方法,并以景泰6.2级地震为例,讨论了区分中强以上地震前的临震突变异常和干扰引起的突变异常的思路和方法。对于地电台站密集地区发生的中强以上地震,在临震前用本文提出的思路和方法有可能对其发生地点和发震时间作出比较准确的预报。

| Abstract: | This paper studied a mathematical method for separating sudden change anomalies from complicated background changes in earth-resistivity, and discussed how to recognize the sudden change anomalies in earth-resistivity due to earthquakes and sudden changes in interferences immidiately before the earthquakes. taking the Jingtai earthquake (6.2) as an example. The result shows that for moderately strong or strong earthquakes which occur in the dense area of geoelectric stations, it seems to be possible to predict the epicenters and the times of occurrence using the method mentioned above immidiately before the earthquakes. |
