摘　　要：激发极化法一直是多金属矿找矿工作中较为有效的物探方法之一。在以前的激发极化法找矿工作中,使用较为广泛的是WDJS-2直流激电仪。近几年随着科技的发展,以GDD为代表的新型激电仪不断涌现。为了比较新型仪器与传统仪器的优劣,选取已知地质条件的地区,对WDJS-2、GDD两种仪器进行对比测试,分析结果认为,GDD电法仪对异常段反应更加明显,具有曲线较光滑、锯齿状跳变少、更易于发现异常等特点。The Induced Polarization(IP)method is one of the most effective geophysical prospecting methods for prospecting polymetallic ore.In the previous induced polarization prospecting,WDJS-2 is widely used.In recent years,with the development of science and technology,new type of IP devices represented by GDD are emerging.Comparing and testing two instruments in the area with known geological conditions.The results show that the GDD instrument has better response to the abnormal segment.The curve is smooth,and the sawtooth change is less,It is easier to find anomalies and other characteristics.
