| 摘 要： | 对金电极在酸性含氯离子的溶液中的恒电位电化学振荡行为，提出了一个可能的非连续型振荡的系统动力学模型，得到了参数坐标空间中的动力学行为区域图，并在振荡区内通过数值模拟方法得到了振荡曲线，其结果能较好地与实验报道相一致

| Abstract: | A dynamic model of current relaxation oscillation of gold potentiostatic electrodissolution in acidic chloride solution is proposed.The regimes of dynamic behavior in the parametric plane are obtained,then the current oscillation curves are calculated by the way of numberical integration when oscillation appears in the electrochemical system.The theoretical results are in good qualitative agreement with experimental observation reported in literature. |
