【Abstract】 The further study on the trend geomagnetic anomalies occurred in the north part of Shanxi is made using the method of the geomagnetic difference annual variation rate,and the explanation for the curve of the difference annual variation rate is made also,the corresponding analysis for the anomalies of the difference annual rate δF is made combining with the earthquake at Yingxian of May 15,1999.更多还原
