| 摘 要： | 利用元胞自动机Q2R／WQ2R方法研究了二维微正则Ising模型的临界相变，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，并且观察到了相变临界现象，得到了临界能量．文中确立的方法可以为三维Ising模型的仿真计算打下基础．

| Abstract: | The authors construct a microcanonical ensemble system and analyzes the phase change of the two-dimensional Ising model Cellular Automata Q2R/WQ2R method. The result indicates that the numerical value simulation can show the spontaneous magnetization of two-dimensional crystal lattice in isolated system. The authors have observed the critical phase transition phenomenon and gotten the critical energy. The simulation of three-dimensional Ising model can be grounded on the method that this article establishes. |
