| 摘 要： | 清理攻关后，虽然相关系数法被列为地磁学科预报地震的方法之一，但应用性较差，且震例不多，为了探讨该种方法预报地震的效果，本文对辽宁地区总磁场强度进行了空间相关分析。

| Abstract: | The correlation coefficient method is still taken as the one of methods for geomagnetic anomaly to predict earthquake during 8th five-Year Plan, but its effectiveness is not good and actual examples are not many.In order to research effect for the method to predict earthquake, we make spatial correlation analysis in the case of total intensity of geomagnetic field in Liaoning area, and research correlation coefficient variation before North Yellow Sea earthquake, M_L = 5.0, on Dec. 31, 1993. The results show that preseismic anomaly is obvious and belong to mid and short range variation. |
