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.
The periodic perturbation of Belousov-Zhabotinsky (BZ) reaction system in a continuous stirred tank reactor (CSTR) was carried out by varying the flow rate as a perturbation parameter to change the perturbation period or perturbation intensity. Under certain conditions, the intrinsic oscillation can be controlled as Based on the four-variable Montanator model of BZ reaction, periodic perturbations of the bifurcation diagram of the corresponding flow velocity region are also carried out. The calculation results agree well with those of the experiment, which shows that for the present system, the mass near the bifurcation point The law of action still has some applicability.
