给出了交流阻抗的理论表达式。极化和a.c.极谱法和伏安法用于两步表面氧化还原反应（Oad+ n1 e\ightleftharpoonsSad，Sad + n2 e\ightleftharpoonsRad），其中电荷转移反应仅发生在吸附的反应物Oad、Sad和Rad之间，并且所有反应物被如此强烈地吸附，以致于可以忽略从电极表面带来或去除的O、S或R的量。吸附的反应物之间的相互作用被假定为由Frumkin的a-参数表示。考虑了双电层阻抗的影响。对几种简化情况进行了详细讨论。
Theoretical expressions are presented of the a.c. polarization and of the a.c. polarography and voltammetry for a two-step surface redox reaction (Oad+n1e\ightleftharpoonsSad,Sad+n2e\ightleftharpoonsRad) in which the charge transfer reactions take place exclusively between the adsorbed reactants Oad, Sad, and Rad, and all the reactants are adsorbed so strongly that the amount of O, S, or R brought to or removed from the electrode surface can be neglected. The interaction between the adsorbed reactants is assumed to be expressed by Frumkin’s a-parameters. The effect of the double layer impedance is taken into account. Several simplified cases are discussed in detail.
