摘　　要：基于二维Ising模型,讨论用Monte-Carlo方法数值模拟正则系综的临界行为.计算结果表明此数值仿真能够显示二维自旋晶格的自发磁化.该文确立的方法可以为三维Ising模型的仿真计算打下基础.Based on two-dimensional Ising model, we simulate the critical behavior of canonical ensemble by Monte-Carlo simulation. The results indicated that the computer numerical simulation can reflect the spontaneous magnetization of two-dimensional crystal lattice. The method built in the paper can provide a basis for the simulation of three-dimensional Ising model.
