研究了碳钢 /H2 SO4 +K2 Cr2 O7/Pt体系中的电位振荡现象 ,如周期振荡、准周期振荡和混沌振荡等 ,并对其振荡机理进行了初步分析和讨论。可以发现 ,在同样的电解质溶液中 ,它同纯铁的动力学行为类似且具有比纯铁更为复杂的动力学行为 ,电解质溶液的成分和浓度对电位振荡的产生起关键作用 ,电极的表面性质也对电位振荡现象产生重要的影响 The potential oscillations in carbon steel / H2 SO4 + K2 Cr2 O7 / Pt system were investigated, such as periodic oscillation, quasi-periodic oscillation and chaotic oscillation. The oscillation mechanism was also analyzed and discussed. It can be found that in the same electrolyte solution, it has a similar kinetic behavior to pure iron and has more complex kinetic behavior than pure iron. The composition and concentration of the electrolyte solution play a key role in the generation of potential oscillations. The surface of the electrode The nature of the phenomenon of potential oscillations have a significant impact
