| 摘 要： | 通过对新沂地电场平静时段资料与地磁场资料对比分析,结果显示:新沂地震台地电场变化和变化磁场密切相关,其中NS向的主体变化和地磁场H分量的变化准同步；EW向主体变化虽与地磁场H分量变化有相同之处,但其变化形态与其反向,且不尽相同.运用快速傅里叶变换进行频谱分析,发现:新沂地电场NS向和EW向与地磁场H分量的优势周期存在不... |

| Abstract: | The spectrum of quiet-day geoelectric field Xinyi Seismic Sation are comparatively analyzed. and the geomagnetic field H component in The result showed that： the changes of ge oelectric field and the magnetic field in Xinyi Seismic Station are closely related. The changes of the NS component of the geolectric field and the H component of magnetic are pseudo syn- chronous; while the changes of EW component of geoelectric field and the H component of magnetic field are similar, but with reverse shape. Using FFT spectrum analysis, it is shown that there are different correlation between NS and EW component of geoelectric field with the geomagnetic field in dominant period. This result explained one important mechanism of geoelectric field in the Xinyi Seismic Station. |
