大地电磁相位张量分解特性

摘要

在大地电磁资料的分析中，其中相当大的一部分问题都是因为近地表电性结构水平非均匀性导致二维或三维的区域构造中水平均匀的正常电磁场发生畸变，从而对MT阻抗张量产生影响[1]。故研究MT阻抗张量畸变和分解方法对于反演解释的正确性有重要的意义。%In magnetotelluric data analysis, a considerable part of the problems are due to the distortion of even level normal electromagnetic field in the 2D or 3D regional structure led by the uneven level of near-surface electrical structure, thus influencing the MT impedance tensor. Therefore, Researching the MT impedance tensor distortion and the decomposition methods is important for the correctness of the inverse interpretation.
