| 摘 要： | 利用转换函数的方法对乾陵、泾阳、周至台1991—2002年地磁资料进行了计算处理，对关中各台地磁转换函数的变化特征进行了初步分析探讨。结果表明：不同周期的转换函数A、B以及总方差σz和△αρ在震前有明显变化；转换函数异常幅度不仅与周期有关，也和地震的震中距和震级有关。

| Abstract: | Based on the geomagnetic data of Guanzhong, Jingyang and Zhouzhi areas from Jan. 1991 to Jun. 2002, the monthly variation of the modules ｜A ｜ and ｜ B｜ of transfer characteristic A and B and total variance σz were analyzed by the transfer characteristic method. The results show that different periods transfer characteristic A and B, total variance σz and αρ changed greatly before earthquakes, and anomalous amplitude of transfer characteristic not only related with the earthquakes periods but also with the epicentral distances and their magnitudes. |
