| 摘 要： | 直流激发极化法，计算视电阻率的一次场采集于供电方波的末端时间，从而包含了被激发形成的二次场。在高极化率地质体上，得到的视电阻率将削弱其低阻特性或放大高阻特性。为此，建议在野外工作中，应对所采集的一次场作适当的处理后，再计算视电阻率，以降低这种影响。

| Abstract: | Caculated apparent resistivities by direct current induced polarization method is collected from the terminal time of power supply square wave the collected data include the second field formed by induction. Apparent resistivity will be the lower resistivity, but enlarge the higher resistivity on the geological body with high polarization. Therefore, it is suggested that the collected data of Primary field should be Processed before caculation of apparent resistivity in order to lower the above-mentioned influences. |
