| 摘 要： | 在Chlorine-iodine-malonic-acid反应扩散体系中,研究了时间延迟反馈对体系时空动力学的控制作用。首先,理论分析发现调节延迟时间和反馈强度会影响体系霍普夫分岔行为。其次,数值模拟发现时间延迟反馈可诱导体系从稳定定态、图灵斑图态向螺旋波态、整体振荡态的转变。

| Abstract: | The effectice of time-delayed feedback on pattern formation in Chlorine-iodine-malonic-acid reaction-diffusion system is studied.We analyze the linear stability and obtain the system's Hopf bifurcation behavior controlled by varying the feedback parameters(delay time and feedback intensity).Moreover,numerical simulations show that the transition from stable steady state,turing pattern to spiral wave state and bulk oscillation state can be induced by time-delayed feedback. |
