中文摘要：
采用Greenberg—Hasting元胞自动机模型，在零流边界条件下计算机数值模拟研究激发介质中行波的性质。结果表明，行波波速随邻域半径增大而增大，随激发域值增大而减少。得到了系统激发条件与邻域半径、激发阈值的关系，并据此解释了行波波速随激发阈值、邻域半径的变化关系。
英文摘要：
Plane waves in the two dimensional excitable media are simulated on computers using the Greenberg-Hasting cellular automata model with the no-flux boundary conditions. The results show that the velocity increases when the neighbor radius grows,and decreases when the excitation threshold increases. The relationship is obtained between the excitation condition of the system and the neighbor radius and the excitation threshold,which explain the relationship between the velocity of plane wave,the excitation threshold and the neighbor radius.
