| 摘 要： | 求解异常电位的边界单元法对电测深资料进行地形改正,应用效果明显。在异常电位法中将异常电位与正常电位相加,得总电位,用这种方法得到的总电位比直接求总电位的精度高得多。 |

| Abstract: | The topographic correction of the electric sounding data by the boundary element method for anomalous potential is discussed,and the significance effect is obtained.In the anomalous potential method,the anomalous potential plus the normal potential equals to the total one.The accuracy of the total potential obtained by this method is much higher than that immediately obtained by the boundary element method. |
| Keywords: | electric sounding boundary element method anomalous field topographic correction |
