| 摘 要： | 视电阻率定义在电法勘探中得到广泛的应用。目前在频率域电磁法中常常采用远区视电阻率定义。由于在频率域中收发距并非足够大,以致在低频段远区定义视电阻率往往不能反映地下电阻率值。我们定义全区电阻率及引入校正系数K,经二层三层模型及野外实测资料的计算,证明了方法的有效性。

| Abstract: | The apparent resistivity definition is used in the electrical prospection. At present, the far-zone apparent resistivity definition is usually used in the frequency domain electromagnetic methods. But since the distance between transmitter and receiving location is not sufficiently large in the frequency sounding methods, the far-zone apparent resistivity doesn't reflect the actual resistivity value on the lower frequency. The writers give definitions to the "whole-zone definition" apparent resistivity and introduce correction factor K.The calculation of the two-layer or three-layer models and the field measurement data proves that the method is effective. |
