摘　　要：本文报道使用Ｇ１算法改进了积分方程数值解的一种电化学数值模拟方法，并用它模拟研究了未补偿溶液电阻对快扫循环伏安曲线的影响，分析了充电电流和法拉第电流的耦合效应，对有效电势校正法和背景电流扣除法的误差来源和可能的消除方法进行了探讨．An improved by G1 algorithm for solving the integral equations electrochemical numerical simulation method is reported. This method was applied successfully to simulate fast cyclic voltammograms with existing of the uncompensated solution resistance (R u) and double layer capacitance (C dl ). The influence of R u , the coupling of charging and faradaic currents were investigated. Effectiveness of the correction method by using effective potentials and the background subtraction method was discussed.
