摘要
简单总结了已有BR(Briggs-Rauscher)振荡体系的机理模型的特点和不足之处,并构造了一个能模拟HIO2、I2、I和O2四个组分的9步反应机理的简化模型.该模型能在较大的初始输入组分浓度范围内出现周期性的振荡行为,可用于解释BR体系中的一些特定的实验现象,并且能够呈现极限环和双稳态.
Many features and disadvantages of reaction mechanisms and models suggested for BR (Briggs-Rauscher) oscillatory system are summarized briefly in this paper. Moreover, a simplified model for a nine-step reaction mechanism is proposed which can simulate concentration variations of the following four species HIO2,I-2, I- and O-2. The model exhibits periodic oscillatory behavior in a wide range of initial concentrations of inflow species, and can be used to elucidate some special experimental phenomena. Additionally, limit cycle and bistabilty are observed in this model.
