摘要
利用扩展的三变量布鲁塞尔模型,得到了新的时空斑图,其中包括振荡四边形斑图、调制条纹斑图以及螺旋波斑图.通过对模型进行线性稳定性分析,发现这些时空斑图是由于短波不稳定性所引起的.另外,还研究了系统大小对时空斑图的影响.
New spatio-temporal patterns including oscillating square pattern, modulated stripe pattern and spiral pattern have been found in a three-variable Brusselator model. It is found that these pattern are caused by short-wave instability through the linear stability analysis. In addition, the effect of system size on the patterns has been also studied.
