摘　　要：为了适应地震短期预报的需要，应用地磁差值年变率方法，取得了1995年10月6日唐山5．0级地震δF异常短期（3个月）追踪图像。依据δF异常（测点数量、幅度、空间分布的大小和方向）时空演化过程和演变特征，进行地震短期预测追踪的尝试。This paper has studied the anomaly of annual variation rate of the geomagnetic difference value before two Tangshan moderately strong earthquakes, based on the comprehensive analysis of the data, observed from 40 stations in the Capital Circle Area from 1988-1996. The analytical result shows that it is a near-field precursor example for the earthquakes with better seismomagnetic relation. This method is applied to annual judgement ofearthquake trend for four years.
