| 摘 要： | 通过对石墨、铜及若干个金属矿区的矿石标本进行实验研究,系统地观测了它们的时间谱和电流谱.根据实验结果,标本的时间谱和电流谱的阴、阳极优势情况有两种基本类型.以电化学理论为基础,对产生这两种基本类型的机理作出了解释,认为这与标本的可溶性与否有关.在一定条件下,根据谱的阴、阳极优势情况识别极化体的可溶性和不可溶性是可能的.

| Abstract: | Through experimental study of graphite, coppor and ore specimens fromseveral ore districts in a water tank, the authors systematically observed theirtime spectra and current spectra. The electrode superiority of their time spectraand current spectra divides them ioto two basic types. On the basis of electroche-mical theories, the mechanism responsible for these two basic types are accou-nted for, and it is held that this might hare something to do with solubility ofthe specimens. Under certain conditions, it is possible to distinguish solubility and insolubility of the polarized bodies according to electrode superforities ofthe spectra. |
