摘要
这里研究层状极化介质激发极化效应特征。首先,在忽略电磁效应的情况下,用柯尔～柯尔模型表征极化介质复电阻率,计算三层不同地电断面复电阻率的振幅和相位随极距变化的曲线;然后,分析极化层不同充电率和不同时间常数、不同激发频率和极化层不同埋深,对测深曲线的影响规律,并提出了具有实际指导意义的极化层埋深与极距的对应关系。这些工作都能够为野外开展复电阻率测量和资料解释起到参考作用。
This paper mainly studied the induced polarization effect of layer mediam with polarization. Firstly,without considering the case of electromagnetic coupling,it calculates the curves which illustrate that the complex resistivity s amplitude and phase make changes along with the polar distance under condition of three different geoelectrical sections;Then,it comes to analyze the regularity of the curves influenced by different chargeability and time constant of the polarized layer, different frequency and different polarized layer s depth.Moreover,it proposes the relationship between polarized layer s depth and the polar distance, which practically plays a significant guiding role.
