| 摘 要： | 地磁场转换函数在强震前会发生变化，这已被广泛公认。利用汶川周围9个“十五”建设的地磁台站分钟值数字记录数据，分析和研究了汶川地震前的地磁转换函数变化特征，结果表明：汶川地震的发生与周边台站地磁转换函数异常的关系是明显的，地磁短周期转换函数方法是一种物理意义明确、并有一定预报效能的好方法。

| Abstract: | The variation of transfer function in the geomagnetic field before strong earthquake has been widely recognized.In this work,by use of the minute value data recorded at nine geomagnetic stations around Wenchuan,we analyze the pre-seismic characteristics of the transfer function.The result indicate that there is a close relationship between the occurrence of Wenchuan earthquake and the abnormal variations of geomagnetic transfer function in the neighboring stations.It is confirmed that short period geomagnet... |
