| 摘 要： | 利用电荷传输方程研究了图灵-霍普夫切空间的二维斑图动力学.研究发现,在该空间存在图灵模与霍普夫模的竞争现象.通过分析斑图的时空特性研究了竞争过程中图灵模与霍普夫模的主导作用.模拟结果表明,在切空间附近,微扰的大小也影响竞争的结果.

| Abstract: | The 2D dynamics of patterns near codimension-two Turing-Hopf bifurcations are studied with charge transport equation.It is found that there exists competition between Turing mode and Hopf mode in this space.The leading effect of Turing mode and Hopf mode during competition is investigated by analyzing the spatiotemporal characteristics of patterns.Simulation shows that perturbations also affect the competition results. |
