| 摘 要： | 以流速为扰动参数,对连续搅拌釜式反应器(CSTR)中的Belousov-Zhabotinsky(BZ)反应体系进行周期扰动,改变扰动周期或扰动强度,在某些条件下,本征振荡可以扰动控制为另一类周期振荡形式,以BZ反应的四变量Montanator模型为基础,对相应流速区域的分叉图进行了周期扰动,计算结果与实验基本定性一致,表明对本体系而言,在分叉点附近质量作用定律依然具有一定的适用性。

| Abstract: | The periodic perturbations on oscillatory states of CSTR - BZ reaction is studied by alternating flow rate in the experiment. Dynamic responses of different oscillation forms have been observed. Bifurcation diagram is calculated based on the 4 - variable Montanator model of BZ reaction with or without perturbation by flow rate signal. Our experimental results obtained in BZ reaction are in good agreement with the Montanator model simulation, which indicates that the mass action law still has certain application near bifurcation in this system. |
