Numerical simulations of a simple reaction-diffusion model reveal a surprising variety of irregular spatiotemporal patterns. These patterns arise in response to finite-amplitude perturbations. Some of them resemble the steady irregular patterns recently observed in thin gel reactor experiments. Others consist of spots that grow until they reach a critical size, at which time they divide in two. If in some region the spots become overcrowded, all of the spots in that region decay into the uniform background.
数值模拟一个简单的反应扩散模型揭示了令人惊讶的各种不规则时空模式。这些模式是对有限幅度的扰动的响应。其中一些类似于最近在薄凝胶反应器实验中观察到的稳定不规则模式。其他模式由斑点组成，这些斑点会不断生长，直到达到临界大小，此时它们会一分为二。如果在某个区域斑点变得过于拥挤，该区域的所有斑点都会衰减到均匀背景中。
