摘　　要：用元胞自动机Q2R规则来模拟微正则系综的临界行为,同时考虑到二维Ising模型[2]的同步演化.计算结果表明,此数值仿真能够显示二维晶格在孤立条件下的自发磁化.可以为三维Ising模型的仿真计算奠定基础.The authors simulate the critical behavior of microcanonical ensemble by the Cellular automata Q2R rules and consider the in - phase evolvement based on two - dimensional Ising model. The results indicate that the computer numerical simulation can reflect the spontaneous magnetization of two - dimensional crystal lattice under the isolated condition. The method built in this paper can provide a basis for the simulation of three - dimensional Ising model.
