摘　　要：推导了微环电极上双电位阶跃计时电流和计时库仑法可逆波理论方程式，并得到了解析表达式。对其电流电量曲线的特性进行了讨论。在亚铁氰化钾－氯化钾体系中，用金微环电极在自制的微机多功能电化学仪器上进行了实验验证，实验结果与理论相符。In this paper,analytical expressions for double step potential chronoamperometry and chronocoulometry with simple reversible electrode reaction at microring electrodes are derived.In order to examine the validity of the theory,experiments were carried out on gold microring electrodes with K4Fe(CN)6 in 0.5 mol/L KCl solution.The experimental results are in good agreement with the theoretical ones.
