| 摘 要： | 文章在综合双频激电法和相位激电法基础上,首次提出了双频激电相位法,该方法通过分析两个较低频率电流的激电相位差来达到地质勘探的目的.基于COLE-COLE模型,对双频激电相位法进行了理论分析,针对不同类型岩矿石作了数值模拟与物理模拟,从理论分析和模拟的结果可以发现,该方法既能反映地下岩矿石的激电效应强弱,也能在一定程度上反映其时间常数大小,因而可用于极化异常体性质的区分.

| Abstract: | Dual frequency IP phase method is to analysis IP phase difference of low and high frequency. The method has the excellence of dual frequency IP method and phase IP method. Theccetical derivation, numerical simulation and physical simulation about dual frequency IP phase method are discussed in detail. It is shown that the method can reflect IP effect degree of certain geologic body and its time constant value. So, dual frequency IP phase method can be used to distinguish character of anomalous geologic body. |

| Keywords: | dual frequency IP phase IP effect time constant character distinction |
