摘　　要：尽管大量关于枝晶生长模拟的研究都使用了相场方法,但近年来元胞自动机(CA)方法在枝晶生长模拟方面也取得了很大进展。介绍了CA方法模拟枝晶生长的原理和模型,评述了CA方法在枝晶模拟方面的发展历程,指出了存在的问题的和进一步研究的方向。Recently cellular automaton method has made great progress in simulating dendritic growth while research on this subject was mainly implemented with phase filed method. In this paper, the principle and model of dendrite simulation with CA method were introduced, the development of which was reviewed and the problem to be further studied were pointed out.
