A model reaction-diffusion system with two coupled layers yields oscillatory Turing patterns when oscillation occurs in one layer and the other supports stationary Turing structures. Patterns include "twinkling eyes," where oscillating Turing spots are arranged as a hexagonal lattice, and localized spiral or concentric waves within spot-like or stripe-like Turing structures. A new approach to generating the short-wave instability is proposed.
一个具有两个耦合层的模型反应扩散系统，当一层发生振荡而另一层支持静态图灵结构时，会产生振荡图灵模式。模式包括“闪烁的眼睛”，其中振荡的图灵斑点排列成六边形晶格，以及在点状或条纹状图灵结构内的局部螺旋波或同心波。提出了一种产生短波不稳定性的新方法。
