PO反应混沌特性的理论研究

The Theoretical Analysis of Chaotic Behavior in PO Reaction

采用非线性稳定理论的分析方法 ,对peroxidase oxidase反应 (PO反应 )所呈现的混沌态进行了理论研究 .通过计算PO反应系统的最大Lyapunov指数 ,判定该系统失稳后的演化模式为混沌态 ,数值模拟反应物O2 浓度随时间变化的混沌曲线与实验测定的混沌曲线相吻合 .

The chaotic state presented in peroxidase-oxidase reaction (PO reaction) is researched theoretically by means of analytic method of nonlinear stability theory. The maximum Lyapunov index in the reaction is calculated,the conclusion shows that the evolution pattern of the system is chaotic after it becomes unstable,and the chaotic curve drawn by changing density of reactor O 2 in accordance with time is identical to the chaotic curve measured by experiments.
