| 摘 要： | 用华北地区十二个地磁台资料，用时空变量统一拟合法，得到地磁场理论模型。然后消去时，空两方面的正常背景，利用剩余场来探寻地震的中长期前兆，密集等值线分布与应力方向和构造单元的走向是大体一致的，这说明利用地磁场来监视应力的积累过程也许是可能的，最后，给出了未来１－３年强震危险区初步的预报意见。

| Abstract: | In this paper,using the data of 12 geomagnetic observatories and applying the method of uniform temperal spatial elements fitting,the theortical model of geomagnetic field has been obtained.After removing the normal field and the space disturbance,the distribution of abnormal field in some locations have been drawn.The distribution contour lines are consistent with the stress distribution and tectonics.The prelimanary results show that this mothod is of vast prospect in earthquake prediction. |
