大连及邻区在1981~1991年间发生了多次中强地震。本文作者应用地磁加卸载响应比方法对大连台1981~1991年地磁资料进行处理。在研究大连台P(Z)值的异常变化与该台周围中强地震关系的基础上，给出映震异常的定量指标及预报效果。
There were many moderate-strong earthquakes in Dalian and its neighboring areas from 1981 to 1991. The author applied the geomagnetic loading-unloading response ratio method to process the geomagnetic data of Dalian Station from 1981 to 1991. Based on the study of the relationship between the abnormal change of P (Z) value in Dalian and the moderate-strong earthquake around this station, the quantitative index of earthquake anomaly and its prediction effect are given.
