作为野外生产第一线的工作者,有时会遇到物探电法中梯装置下,激发极化法视幅频率FS参数为负异常的问题。本文初步研究讨论、总结归纳实际工作环境中,激电异常会出现负值的3大类可能原因,并罗列了许多野外观测发现的重复现象,但没有在理论上给出一定的解释依据。 As the first-line workers in field production, they sometimes encounter the problem of negative anomalies in the amplitude-frequency FS parameters of the excitation polarization method under the geophysical method. In this paper, preliminary research and discussion are summarized to summarize the possible causes of the three major categories of negative anomalies in the actual working environment and to list the repeated phenomena found in many field observations. However, no explanation is given in theory.
