| Abstract: | The distribution characteristics and laws of underground current for a change current system with the opposite direction are indicated in this paper. Secondly, anomalous formulations of the apparent resistivity in resistivity method with the opposite change current system are given, and a relation between the array factor and the allotment current factor is calculated, its laws and significance are showed by the results of calculations. Finally, as examples, the anomalous laws of the apparent resistivity in electrical sounding method with the opposite change current system of level layers and spheres are analysed, as well as the significance for exploration is pointed out. |
