| 摘 要： | 针对三维／二维地质结构开发了大地电磁阻抗张量分解技术，利用该技术仅需对各个独立测点的大地电磁资料进行分析即可分离和消除由三维局部异常体引起的其附近测点的ＭＴ响应函数的形态扭曲畸变。

| Abstract: | Just for 3-D/2-D geological structures,the decomposition technique of MT impedance tensor is developed.It can separate and remove the twist distortion of MT corresponse function shape resulting from 3-D local abnormal objects near surveying site by using the technique to analyze the MT data of each independent site.The theoretical model tests in this paper have shown the effectiveness of the technique in removing the local distortion. |
