由水平薄层电导率结构假设,引入了对电导率结构异常区感应中心的水平磁场响应传递函数,通过对垂直磁场予测,可分离出垂直磁场异常。再经向下延拓到薄层电导率异常体表面,有可能求得反映局部地区电导率异常的等效水平电流异常图象。 Based on the horizontal thin-layer conductivity structure, a horizontal magnetic field response transfer function is introduced for the sensing center in the abnormal zone of conductivity structure. By predicting the vertical magnetic field, the vertical magnetic field anomaly can be separated. Then it extends down to the surface of thin-layer conductivity anomalies, so it is possible to obtain the equivalent horizontal current anomalies that reflect the conductivity anomalies in some areas.
