【Abstract】 The electrochemical oscillations often are observed in the process of anodic electrodissolution of metal and alloy, in particular, in the transitional period of between activation and passivation. The various current oscillations,such as damp oscillation, periodic oscillation, quasi-periodic oscillation and chaos,can arise in the narrow range of potential where occurs the process of activation-passivation in the system of Carbon Steel/H 2SO 4/Pt, and its oscillatory mechanism is preliminarily discussed.更多还原
