| 摘 要： | 通过观测实例,对传统流动地磁观测震磁信息提取方法中存在的参考值问题进行了讨论,提出了一种以测区内可信测点F测值变化平均值作为地磁场正常变化参考值的处理方法。该方法提高了信噪比,使测区震磁信息的提取更具合理性。

| Abstract: | The problem of reference value confirmation by using the traditional methods to extract seismomagnetic information from geomagnetic survey data is discussed with observational examples.A new method,which uses the mean value of F at crelible sites in the measuring region as reference value of geomagnetic field,is presented.The method increases the ratio of signal to noise,and makes the extraction of abnormal information more rational. |
