【摘要】 应用地磁Z21差值法、日变空间相关系数法及幅相法，对1995年9月20日山东苍山MS5．2级地震前江苏地磁台网记录的综合磁异常特征进行了初步分析。其结果对利用江苏地磁台网预测5.0级以上地震具有一定的现实意义。更多还原

【Abstract】 The comprehensive character of geomagnetic anomaly in Jiangsu province gromagnetic network prior to Changshan Ms5. 2 earthquake in Shangdong province on September 20, 1995 has been reflected and analysed with Z21 value deference method, daily varition correlation coefficient method and amplitude-phase method. It is of great significance to the prediction of Ms> 5. 0 earthquakes in Jiansu geomagnetic network afterwards.更多还原
