摘要
用复数电容的概念推导了电化学体系中理想极化电极、电化学极化电极及兼有电化学极化和浓差极化电极的复数电容表达式．根据表达式分析了上述体系的电容平面图（ Ｃａｐａｃｉｔａｎｃｅ Ｐｌａｎｅ Ｐｌｏｔ， Ｃ Ｐ Ｐ），利用 Ｃ Ｐ Ｐ可以方便地监测体系的电容值．用电子元件或实际电极构成了上述体系的等效电路，测定了交流阻抗谱，得到的 Ｃ Ｐ Ｐ
The exprassions of complex capacitance for ideal polarized electrodes,kinetic controlled electrodes,and both kinetic and mass transfer controlled electrodes,were deduced.The capacitance plane plots(CPP)of these electrodes were analyzed based on the expressions.Using CPP,the capacitance of working electrode can be conveniently monitored.The deduced expressions and CPPs of the above mentioned electrodes were confirmed by experimental results of equivalent circuits composed of electronic elements.
