摘要: 对H2SO4/NaCl溶液电解Cu体系中出现的Shilnikov混沌特性的拟合计算进行了改进,求出了体系的Lyapunov指数,确定出体系存在混沌吸引子,并且发现计算机模拟出的混沌吸引子的形状与实验得出的吸引子十分相似.

关键词: Shil'nikov混沌, 稳定性, Lyapunov指数, 混沌吸引子

Abstract: Fitting calculation about Shil'nikov chaotic behavior of system performed on electrodissolution of Cu in a H2SO4/NaCl solution is improved, and the Lyapunov index is obtained. It is proved that there exists a chaotic attractor in this system. The chaotic attractor of the numerical simulation is consistent with the experimental one.

Key words: Shil'nikov chao, Stability, Lyapunov index, Chaotic attractor
