利用正负极差法评价激电异常的理论和实验结果

The Theory and Experiment Results on Applying Positive and Negative Polarization Difference Method to Evaluate IP Anomaly

从电化学理论上讨论了阴极、阳极过电位与电流密度的关系。提出了极化柱体上极差电位的表达式,分析了影响极差电位的诸因素。从实验中得到了几种极化体的极差电位电流谱、时间谱及极差电位剖面曲线。表明正负极差法对激电异常的评价是有效的。

The authors discussed the relationship that the overvoltage of cathode and anode are varied with the current density in terms ofthe electrochemistry.The solution of polarization difference potential (PDP) on a polarizable cylindric body is put up.Some experi-ment results are got.It will be seen from this that positive and negative polarization difference method is efficient on evaluating IPanomaly.
