超长时间激发下不同类型极化体激发极化场的非线性研究

THE NON-LINEAR STUDY ON THE POLARIZATION FIELD OF SEVERAL TYPE POLARIZABLE BODY IN THE CONDITION OF OVERTIME INDUCING

针对非线性极化条件下矿体的电化学过程的特点，从电极化和电极阻抗的角度，阐述了电化学反应对极化体充电过程的影响．对于离子导电岩石，极化率与岩石构造参数γ，密切相关，对于电子导电的极化体，极化强弱与金属－电解液界面的电极阻抗有关。实验表明，非线性极化条件下，极化体在充电一段时间后会出现一个激电场的极大值，而且不同类型的极化体激电场极大值出现的时间不同，这为区分激电异常源的性质提供了可能。

According to the properties of ore electrochemical effect in the condition of non-linear Polarization, this paher has explained an influence on charge curve by electrochemical reaction from the angle of electro-polarization and electrode resistance. The polarizability ot electric conduction ore by ion is relative toγand which are ore's structural parametes, and the polarization of electric conduction polarizable body by el.ectrion is relative to electrode resistance in the surface of metal-electroliquid. Experiment indicates that an extreme big value will appear after a while when polarizable body was recharged. The times of extreme big value of polarization field are variable to several type polarizable bodies, it gives the possibility to distinguish the property of polarization anomaly source.
