频率测深的地形影响及其校正方法

从含源麦克斯韦方程出发，按照二维地形条件下的线源非齐次赫姆霍兹方程确定其边界条件，用边界元法计算了起伏地形条件下线源的频测影响曲线，并将其转换为二维地形点源赤道偶极装置频测曲线。总结了地形对频测曲线影响的规律，提出了地形校正的方法。

THE EFFECT OF THE TOPOGRAPHY ON FREQUENCY SOUNDING CURVES AND THE CORRECTING METHOD

rom bear-source Maxwell equation, the paper, in accordance with line-source non-even Helmholtz equation under conditions of two-dimension topography,defined the boundary conditions. With the use of boundary element method, E. M. frequency sounding curves affected by undulate topography are computed, and the converted to the topography effects on frequency sounding curves of two--dimension topography by way of point--source equator device. The rule of that topography affects frequency sounding curves is sumed, and correcting method is found out.
