| 摘 要： | 研究一类具有常系数扩散项的系统,讨论了系统出现Turing不稳定性的条件.结果表明,在反应项满足一定条件下,只有当扩散系数不同时才可能出现Turing模式.最后,给出了系统发生Turing分支时两个不同扩散系数的临界比值.

| Abstract: | In this paper,a type of reaction diffusion systems was studied,the sufficient conditions of the Turing instability are obtained.Under certain hypotheses to reactions,Turing pattern can been create only if the system have inequality diffusion constants.The ratio of critical value on two different of the diffusion constants when Turing bifurcation to appear were given. |
