我们提出了在锌的薄层电沉积中观察到的界面振荡的全局解释。基于对电压信号的分析和金属聚集体的数字化图像，我们的实验研究揭示了电化学节律性的新机制。我们主要讨论了在受限几何结构（准二维电解质层）中工作电极附近锌离子的强耗竭和质子的竞争性还原之间的基本竞争，这是时空集体界面动力学的关键机制。
We propose a global interpretation of the interfacial oscillations observed in the thin layer electrodeposition of zinc. Based on the analysis of voltage signals and digitized pictures of the metallic aggregates, our experimental investigation reveals clues to a new mechanism for electrochemical rhythmicity. We discuss mainly the fundamental competition between the strong depletion of zinc ions in the neighbourhood of the working electrode in a confined geometry (quasi-two-dimensional layer of electrolyte) and the competitive reduction of protons as a key mechanism for spatiotemporal collective interfacial dynamics.
