在常规激发极化法(IP)所取得的数据中,实际上还包含有直流电阻率的信息。但如果要求获得的电性信息量达到最大,则必需在额外的交流电频带上测量电阻率的实、虚两个分量。这种测量方法称为复电阻率法,要求对输出和输入波形的振幅和相位进行比较,经过中间变换,频率域和时间域都被采用。这就可以对整个线性地电系统进行研究。所以,复电阻率(CR)法是一种变频的接地电法,借助于分析大地总电阻率的实分量和虚分量来研究大地的电性。因为这种方法可以得出激发极化的不同参数、电阻率和有关大地的电性和电磁性,区分它们各自的作用,而且把结果显示出来,供观察分析
In the data obtained by conventional induced polarization (IP), the DC resistivity information is actually included. However, if the maximum amount of electrical information is required, the real and imaginary components of the resistivity must be measured on the extra AC band. This method of measurement, called the complex resistivity method, requires the comparison of the amplitude and phase of the output and input waveforms. After the intermediate transformation, both the frequency and time domains are used. This allows the study of the entire linear geoelectric system. Therefore, the complex resistivity (CR) method is a variable frequency grounding method that studies the earth’s electrical properties by analyzing the real and imaginary components of the total earth resistivity. Because this method leads to the different parameters of the excitation polarization, the resistivity and the electrical and electromagnetic properties of the earth, distinguishing their respective effects, and displaying the results for observation and analysis
