中文说明：
正是由于元胞状态的改变使微观组织发生着变化，而元胞状态的改变是基于具体的形核和生长以及捕捉规则，这些规则正是元胞自动机模型的核心，根据结晶过程中的晶粒形核和生长的物理机制建立元胞自动机模型是准确模拟晶体组织的关键。
English Description：
It is because the cellular state changes that the microstructure changes, and the cellular state changes are based on specific nucleation and growth and catch rules, which are the core of the cellular automata model, according to the physical mechanism of Grain Nucleation and growth during crystallization, the cellular Automata model is the key to accurately simulate the crystal structure.
