Abstract

Experimental studies of signals from a controlled source in the middle zone under various geophysical conditions have been performed. In the experiment, five field electromagnetic components were measured in the range 0.3–95 Hz. Based on these observations, the effective conductivity of the underlying surface was calculated and an interpretation of the results was given.

根据接收到的地球-电离层波导有源源中间区域中的电磁场的结果，估算下表面的有效电导率

摘要

在各种地球物理条件下，对来自中部地区受控源的信号进行了实验研究。在实验中，在0.3–95 Hz的范围内测量了五个场电磁分量。基于这些观察，计算了下层表面的有效电导率，并给出了结果的解释。
