研究了振荡反应扩散体系的螺旋波动力学。我们发现了一个新的现象:没有任何全局调制模式的出现,稳定的螺旋波直接破裂。通过研究系统的一维版本和孤立的局部动力学,我们发现局部动力学中的不稳定焦点起着重要的作用。在不同的边界条件下,周期性边界条件下存在螺旋波与行波的过渡,无通量边界条件下存在漂移螺旋波。
We studied spiral wave dynamics in an oscillatory reaction diffusion system. We find a new phenomenon: without the appearance of any global modulation mode, stable spiral waves break up directly. By investigating the one-dimensional version of the system and the isolated local dynamics, we find that the unstable focus in the local dynamics plays an important role. For different boundary conditions (BCs), we find a transition between spiral waves and traveling waves for periodic BCs and drifting spiral wave for no-flux BC.
