摘　　要：激发极化法现被应用于金属、石油矿产资源以及地下水等方面的探测,是目前最有效的地球物理勘探方法之一。激发极化法对电子导电矿物存在反应很灵敏,这种在勘探过程中不仅在供电的同时可以观测到一次电位差,而且在断电后仍然可以观测到缓慢衰减的残余电位差,这种在断电后仍然存在的缓慢衰减的残余电位差,是由电化学作用引起的,当测区内有电子导电的矿体,如金属硫化矿和某些金属氧化矿床存在时,我们将观测到这种电化学作用明显增加,因此这种缓慢衰减残余电位差量寻找金属矿床的重要线索和参考资料。The induced polarization method has been applied in the metals,oil,mineral resources and groundwater exploration,which is at present one of the most effective geophysical exploration methods.Induced polarization method in electronic conductive mineral reaction is very sensitive,this not only in the process of exploration can be observed at the same time in the power supply of potential difference at a time,and can still be observed after power off,slow attenuation of residual potential difference,it is still slow after power attenuation of residual potential difference,is caused by the electrochemical action,when measured in electron conduction of ore body,such as metal sulfide ore and some metal oxide deposits exist,we will be observed in the electrochemical function increased significantly,so the slow decay residual quantity of electrical potential difference looking for metal deposit important clues and references.
