The high resistivity layer shall not be infinitely great or close to surface, otherwise the layer will prevent the current entering the anomaly body and no anomaly will be produced.
而当高阻屏蔽层在平面上趋于无限大而且埋深较大时，这时因进入异常体的电流很小，甚至趋于零，所以地面上观测不到异常体产生的磁异常。
There is no high conductivity layer between the two plate suture zones, on the other hand the crust is an integrated high resistivity body.
两缝合带之间没发现壳内高导层，地壳表现为相对完整的高阻体；
The induced polarization anomaly is character of high in chargeability and low in electrical resistivity which is consistent with the electrical property of copper ore-body.
激电异常表现出高极化率低电阻率的电性特征，与矿区铜矿（体）石具有相同的电性特征。
