| 摘 要： | 以Cole- Cole模型作为IP效应极化模型,研究了CSAMT中存在两层极化层时IP效应对视电阻率的影响,并与一层极化层时IP效应产生的影响作了对比.IP效应对视电阻率幅值和相位的影响主要发生在中低频段；两层极化层和一层极化层对视电阻率曲线形态的影响十分相似,其主要差异在于影响程度的大小上；指出在Cole-Cole模型参数的某些取值范围内,难以区分IP效应是一层还是两层极化层引起的.

| Abstract: | The Cole-Cole model is used to study IP effect of two polarization layer on apparent resistivity of CSAM,then the IP effect of two polarization layer is compared with the one polarization layer’s.The IP influence of the resistivity mainly takes place in the low-middle frequency band.The influence of the two polarization layers and one polarization layer is very similar to the apparent resistivity curve morphology,in which the main difference is the influence of the degree.Finally,this paper puts forward that the Cole-Cole model parameters are within some ranges,so it is difficult to distinguish whether the IP effect is caused by two polarization layers or one polarization layer. |
