摘要
元胞自动机是复杂体系的一种理想化模型,特别适合于处理那些难以用数学定量描述的复杂动态体系问题如材料的组织结构演变问题,尤其适合于计算机模拟实施。本文使用元胞自动机模型根据最基本的物理学原理和温度场模拟计算耦合,得到了枝晶的生长结构。由于本模型没有引用微观研究中关于枝晶的特殊理论,因此可以将这种结果看做是通用模型的一种特殊情况。这说明:元胞自动机模型除了能够完成对于微观结构的模拟以外,还特别适合于其机理的研究。
Cellular Automata are idealizations of complex systems. They are especially advantageous for modeling complex dynamic problems such as the evolution of microstructures in materials, and are very easy to implement in computer simulation. Dendritic crystal growth was generated via basic physical model and combined temperature field simulation. Since the theory of dendritic crystal growth was not considered in the simulation, these result were some special result under special conditions. Which means that cellular automata is not only a tool of simulation but also a powerful tool for mechanism research.
