| 摘 要： | 电子导体的极化暂态特性与电子导体的性质有密切关系。差异激电法的观测参数─激电差△P能够反映这种特性。本文用极化暂态特性的理论对石墨板、铜板和铁板三种模型上激电差△P异常的基本形态各不相同的现象作了初步解释,说明根据激电差△P异常的基本形态可以把不发生阳极溶解、不可逆性较弱和不可逆性较强的矿石─围岩溶液体系区分开,并且可以剔除炭质干扰。文中还给出了野外试验结果和应用实例。极化暂态特性反映的信息量很丰富,进一步研究有利于激电异常的区分和场源性质的识别。

| Abstract: | The transient state characteristics of the electronic conductor are closely related to the properties of the electronic conductor. The observational parameter of the differential induced polarization method, namely the IPdifference △P, can reflect such characteristics.Using the theory of polarization transient state characteristics, the present paper makes a preliminary interpretation on the phenomenon that the basic shapes of IPdifference △P anomalies on three sorts of models (graphite plate, copper plate and iron plate)are different from each other. It is pointed out that on the basis of the basic shapes of IPdifference △P anomalies, one may distinguish anode-insoluble, weakly irreversible and strongly irreversible ore-wall rock solution systems and can eliminate interference of carbon matters. Field test results and application examples are also given in this paper. Information reflected by characteristics of polarization transient state is very abundant, and hence further research can help to distinguish IPanomalies and differentiate properties of field sources. |
