| 摘 要： | 讨论了地壳介质中常见的两类电性各向异性。推导了长波长条件下薄中向异性电导率张量；提出了一种新的电导率物理模型并由此推导了与ＥＤＡ裂隙相适应的各向异性电导率张量。从直流电法和大地电磁测深法的角度分别讨论了这两种电性各向异性所显现的地表视电阻率、阻抗和电位特征。

| Abstract: | Two kinds of the electrical property constructive relation of anisotropic earth media are discussed in this paper. The ansotropic conductivity tensor of periodical thin layers media is derived, a new 3-D anisotropic model is put forward and its conductivity tensor representative is derived, which is corresponding to EDA medel. Several important equations are introdduced by previous or present authors from the views of electrical resistivity method and electromagnetism approach respectively. |
