化学计量系数对B-Z反应系统动力学行为的影响

实验测定B Z反应系统在其化学计量系数μ取定值1时,其动力学行为呈现单周期振荡态.将化学计量系数μ作为调节参数,理论研究了该系统动力学行为随μ值的变化.结果表明,当μ值从定值变为线性变化参数时,经稳定性分析确定系统存在一个不稳定区域,化学计量系数μ在此区域内取值时,系统均可以呈现单周期振荡态;而当μ从定值变为周期变化参数时,可以确定系统的动力学行为是由倍周期振荡进入混沌.

利用比例脉冲控制B-Z反应中混沌的变量选择

B Z reaction is a typical nonlinear system in chemistry,which can appear oscillation bistability chaos,etc.We have succeeded in the chaos control by use of proportional pulse method and compared the results by use of different controlling variables.It is shown that it is crucial to choose properly the variables for the control of chaos and a proper choise of the variables can make the B Z system stabilized on the expected periodic orbits.
