| 摘 要： | 基于稀释系数不随频率变化的假设,导出了复电阻率视频谱与真频谱及柯尔-柯尔频散视参数与真参数之间的近似关系式。通过对理论视频谱进行的反演和计算证明,即使在稀释系数幅值随频率的相对变化达100%的情况下,选用特征频率的稀释系数值,所导出的视参数与真参数的近似关系式仍有实用价值。从而为频谱激电法资料的反演,计算极化体真参数提供了一种简便而有效的近似方法。

| Abstract: | Based on the assumption that the dilution factor is independent of frequency, the approximate relations between the apparent and true complex resistivity spectra and between the apparent and true Cole-Cole parameters are derived. The inversions and calculations of apparent spectrum show that even if the variation of the dilution factor with frequency changes up to 100%, the approximate relations between the apparent and true parameters are still valid. Then a simple but effective approximate scheme for estimating true Cole-Cole parameters is proposed according to the inverted apparent Cole-Cole parameters. |
