摘要: 对斑图动力学中的Duffet - Boissonade 反应扩散方程组作了一维和二维的数值模拟. 设置了4 种不同的初始条件并按照图灵分岔的条件来选取方程中的参数,模拟得到的六边形斑图和条纹状斑图与实验照片很相似.

Abstract: The one - and two - dimensional numerical simulations of Duffet - Boissonade reaction-diffusion equations in pattern dynamics are performed. Setting up four kinds of different initial conditions and selecting the parameters in the equation according to Turing bifurcation condition,the hexagon pattern and fringe pattern obtained from the simulation are very similar to the experimental results.
