摘　　要：由声光双稳系统的迭代模型出发，构造一种具有外部正弦信号调制的动力学系统，并数值研究声光双稳系统的混沌态在正弦调制下的动力学行为．结果表明，在正弦信号的调制下，系统状态呈现出间歇性混沌及多种演化模式，且随着调制幅度的增大，某些演化模式在一个调制周期内的出现次数增大，系统第一次出现周期窗口所需的迭代次数减小，系统状态的包络振幅增大．另外，调制频率的改变不影响系统的动力学性质。Abstract A new dynamical system under external sinusoidal modulation based on acousto optic bistable iterative model is constructed and investigated numerically.The results show that the state of the system takes on hysterical chaos and several kinds of evolution pattern under the modulation of the sinusoidal signal.As the amplitude of the modulation increases,the number of some evolution patterns in a modulation period will increase,the iterations needed for the first period window of the system will decrease,and the sketch amplitude of the modulated system will increase.In addition,the modulation frequency has no effect on the dynamical characteristics,only changing the number of the evolution pattern.
