| 摘 要： | 通过高密度电阻率法的模型实验,得出不等电极距情况对直立高阻薄板和低阻球体反演结果的影响:缺失电极对它正下方的ρs影响最大,而异常形态主要在水平方向有明显的变化,异常体随电极缺失的位置有趋势变化,电极缺失的数目越多,异常形态变化越大,但是从整体来看反演剖面图基本相似。

| Abstract: | Several special physical models were analyzed and discussed by using the contrastive method in this paper. When some electrodes are lost, the most remarkable change of the resistivity is in the underneath direction, and the anomaly configuration is mostly changed in the horizontal direction because of the location and the number of the lost electrodes. |
