| 摘 要： | 通过对河南荥阳地震台形变观测曲线中的“高频抖动信号”与干扰因素的对比分析，认为这种高频抖动信号有别于干扰信号，具有一定的前兆意义，是地壳形变过程的一种反映，也是一种前兆性异常现象。这种高频信号要在排除风扰等因素后才能够找出其真正的映震前兆信息。

| Abstract: | By comparing high-frequency dithering signals in deformation observation with interference factors of Xingyang seismological station,the high-frequency dithering signal,different from the interference signal,is thought to have certain precursor meaning,which is a kind of reflection of crustal deformation process and can be taken as a precursor anomaly phenomenon,.Only when interference signals,such as wind disturbing,are removed,the real earthquake precursor information of this kind of high-frequency dither... |
