图9 低阻体模型ZTEM倾子响应数据不带地形与带地形的三维反演结果(山峰地形条件) 第一行—5个频率的水平地形ZTEM倾子反演结果;第二行—5个频率的带地形ZTEM倾子反演结果;第三行—8个频率的带地形ZTEM倾子反演结果;第一列—深为500 m的水平切片;第二列—x=0时沿y方向的垂直切片;第三列—y=0时沿x方向的垂直切片;黑色虚线—棱柱体的边界

Fig.9 Results from the 3D inversion of tipper ZTEM data generated from 3D conductive prism model (peak terrain) the top row—the results from the inversion of tipper data (ZTEM) with five frequencies;the second row—the results from the inversion of tipper data (ZTEM) including topography with five frequencies;the third row—the results from the inversion of tipper data (ZTEM) including topography with eight frequencies;the first column—the horizontal slices at 500 m depth;the second column—the vertical slices aty=0 m along the y axis;the third column—the vertical slices aty=0 m along the x axis;the black dashed lines—the prism margins
