Mixed-mode Oscillations in the Hydrogen-Peroxide-Thiosulfate Reaction System

过氧化氢-亚硫酸盐-硫代硫酸盐(H2O2-SO2-3-S2O2-3)反应体系为典型的非线性化学振荡反应体系,该体系存在两个振荡反馈环,使体系表现十分复杂的动力学现象。通过对该体系的动力学机理进行系统的分析和模拟,发现该体系中存在混合模式振荡行为。最后,在实验过程中证实了这一复杂的动力学现象。

Hydrogen peroxide-sulfite-thiosulfate reaction system was a typical nonlinear chemical oscillatory reaction system. There were two oscillatory feedback cycles,which resulted in complex dynamical phenomena. Through systematical analysis and simulation,mixed-mode oscillatary behavior was found in the system,which was proved in the experments the complex dynamical phenomenon was successfully proved in the experiments.
