| Abstract: | Based on two dimensional digital simulation of the frequency electromagnetic sounding with electric dipole supply,the variation characters and static displacement of five kinds of apparent resistivity in wave area are theoretically studied,and the effects of surface local lateral inhomogeneities on distortion of apparent resistivity curves are qualitatively analysed. |

| Keywords: | Electromagnetic sounding Apparent resistivity Static displacement Distortion effect |
