摘要
应用地磁空间相关方法对华北地区１９９６年１月至１９９８年１月地磁核旋定点（北京时２１ｈ）观测数据的分析研究表明，１９９８年１月１０日张北ＭＳ６．２地震和１９９６年５月３日内蒙古包头ＭＳ６．４地震前存在地磁空间相关低值异常。
The fixed point geomagnetic data observed by the nuclear precession magnetometer from January 1996 to January 1998 are analyzed by the method of geomagnetic spatial correlation.The result shows that there exist low value abnormalities of geomagnetic spatial correlation before Zhangbei M S 6 2 earthquake in Hebei Province on January 10,1998 and in Baotou M S 6 4 quake in the Inner Mongolia Autonomous Region on May 3,1996.
