用极化的滴汞电极进行电解电流的研究是极譜学中的一个基本問題。对这类电流的理論分析,包含着解决由于电极过程所引起的、在不断增长的汞滴表面所发生的貭量轉移的問題。电极过程只涉及到电板和能直接交換电子的物貭之間的电子交換时,貭量轉移就构成了法拉第电流,这种质量的轉移,平衡了因电級反应而引起的浓度的变化。 The study of electrolytic current with polarized drop mercury electrode is a basic problem in polarography. Theoretical analysis of this type of current involves the solution to the problem of mass transfer that occurs on the surface of the growing mercury drop due to the electrode process. The electrode process involves only the exchange of electrons between a plate and a substance that can directly exchange electrons. The transfer of the amount of Faraday current constitutes the Faraday current, a shift in mass that balances the change in concentration due to the electrical level reaction.
