摘要
本文用数字模拟方法研究了可逆、准可逆和不可逆电极反应的交流阻抗,得到了与理论推导相符合的结果。文中亦研究了薄层电解池的交流阻抗的数字模拟。通过数字模拟,人们不需用等效电路模型便能解释交流阻抗数据的化学意义,这对认识复杂电极过程尤为重要。文中给出了交流阻抗的离散数字模型,并讨论了动力学参数对阻抗数据的影响。
Digital simulation is employed to study the a.c.faradaic impedance of reversible, quasi-reversible and irreversible electrode reactions. The simulation results accord with the theoretical results very well. The digital simulation of a.c.impedance of thin-layer electrochemical cell is also studied, One does no longer need and equivalent circuitry model in order to interpret the chemical meaning of the impedance data. This is particularly important in the study of complicated electrochemical reactions. In this paper, a discrete model for a.c. impedance is built, the influence of kinetic parameters to the impedance data is also discussed.
