从理论上推导了金属阳极溶解所涉及的几种典型的伴有表面转化步骤的电极过程的交流阻抗表达式．视速控步骤及脱附步骤的不同，电极过程表现出不同的阻抗行为．同时也研究了吸附假电容的产生及在不同反应中的表现方式．对于连续溶解反应，出现低频感抗行为的一个重要特征是假电容为负值；而自催化反应则无上述规律，假电容通常大于０ In this paper, we derive the expression of AC impedance of several typical electrode processes accompanied with surface conversion steps involved in metal anode dissolution. Depending on the speed control step and the desorption step, the electrode process exhibits different impedance behavior. At the same time, the generation of adsorbed pseudocapacitance and the way of expression in different reactions were also studied. For the continuous dissolution reaction, an important characteristic of the low-frequency inductive behavior is that the pseudocapacitance is negative. However, the autocatalytic reaction has no above rules. The pseudocapacitance is usually larger than 0
