本文对共轭电化学反应的法拉第阻抗进行了理论分析,对这种电极的等效电路中的各元件的数值,物理意义以及可简化的条件等作了详细的讨论.指出电极的等效电路相当于雨支阻抗的并联,其中每支阻抗部相应于某一对电化学反应在电极上单独进行时的电极法拉第阻抗. In this paper, the Faraday’s impedance of conjugate electrochemical reaction is theoretically analyzed, and the numerical values, physical meanings and simplified conditions of each element in the equivalent circuit of the electrode are discussed in detail.It is pointed out that the equivalent circuit of the electrode Equivalent to the parallel connection of the rainstop impedances, where each impedance corresponds to the Faraday impedance of the electrode when a pair of electrochemical reactions are performed separately on the electrodes.
