| 摘 要： | 本将关联维的Ｇ－Ｐ法尝试在地磁方法中应用。首先消除外空场的影响，使数据的变化代表地磁场的变化；１２个月为一窗口，滑动步长６个月，以１９９３年１２月日烟台ＭＬ４．８级地震为震例，求分维值。结果表明：地磁场垂直分量的时间序列存在分维结构，而且地震前有明显降维现象。

| Abstract: | The G-P method of association dimension is trying to be used in geomagnetic method. At first, the influence from external space is removed, which makes the data represent the variation of geomagnetic variation. Taking the Yantai earthquake of M=4.8 on Dec. 31 of 1993 as an example, with a window of 12 motnths and steps of 6 month, the fractal values were calculated. The results show that there exists fractal structure in time sequence in geomagnetic vertical component, showing clear dimension reduction before earthquake. |
