| 摘 要： | 用边界无法计算大地电磁Hx型波二维地形影响，并用有限元法计算了起伏地形下水平层状介质的大地电磁响应，用边界元法的结果对畸变后的大地电磁响应进行地形改正，基本恢复了水平地形下层状介质的大地电磁响应的特点．本文给出了物理意义明确、形式简单的视电阻车和阻抗相位地形改正公式．

| Abstract: | A method of calculating 2-D terrain effect on MT for Hx-polarization using the BEM is given. The Hx response of MT for horizontal layered media under irregular terrain is calculated by the FEM, and corrected by the result of BEM. The corrected MT profile basically shows the characteristics of MT response for horizontal layered media under flat ground. |
