摘　　要：激电相位与极化率反映的都是岩(矿)石的极化特性。在某铜矿已知区上进行了试验工作。对比时间域激电测量和阵列相位激电测量的结果,发现与视极化率相比,相位参数对弱极化异常具有更为明显的反应,适合在弱极化区开展工作。Both the phase IP and the polarization rate are important parameters which reflect IP characteristics of rocks or ores. Experi- mental work was carried out in a certain copper mine. Based on a comparison between the results of time domain IP survey and array phase IP survey, the real applying effects show that the phase parameter is more sensitive than IP to weak induced-polarization body. And the method of phase IP measurement is suitable for investigating work in the weak induced-polarization area.
