Belousov-Zhabotinsky (BZ) 反应是化学振荡反应和图案形成的著名实验模型。我们在本文中使用光敏 BZ 反应在实验和理论上研究了具有全局反馈的两个振荡器的扩散耦合系统。耦合振荡器根据扩散耦合和光反馈的强度表现出同相和反相振荡。此外，我们分析了我们的模型以定位分叉原点，并发现反相振荡的分叉分支的重新连接，这是由全局反馈和扩散效应之间的竞争引起的。
The Belousov-Zhabotinsky (BZ) reaction is a famous experimental model for chemical oscillatory reaction and pattern formation. We herein study a diffusive coupled system of two oscillators with global feedback using the photosensitive BZ reaction both experimentally and theoretically. The coupled oscillator showed in-phase and antiphase oscillations depending on the strength of diffusive coupling and light feedback. Moreover, we analyzed our model to locate the bifurcational origin and found the reconnection of the bifurcation branches for antiphase oscillation, which was induced by the competition between global feedback and the diffusion effect.
