| 摘 要： | 针对浅层电性不均匀体引起的大地电磁测深曲线畸变问题，通过二维模拟研究了静态位移规律，具体比较了浅层电性不均匀体对ＴＥ和ＴＭ的影响程度、影响范围、影响性质；指出根据单点一致性和区域一致性，采用曲线平移校正法的避限性，进而提出了静态畸变校正方法的原则。

| Abstract: | MT curve distortion caused by surface electric body is always a question of research on MT.In this paper,the authors investigate static displacement rule through 2D simulation,compare effects of TE with TM by surface electric body and point out the localization of adoption curve level moving correction method based on single point coherence and district coherence Hence they have proposed the fundamental of the static distortion correction method. |
