摘要: 用元胞自动机模型模拟二维伊辛模型的相变临界现象,得出了相变图和时空演化图;当不存在外场时,数值模拟得到的临界温度与理论值精确吻合.

Abstract: The cellular automaton model is used to simulate the critical phenomenon of the two dimensional Ising model. The diagrams of phase transition and space-time evolution are given. It is found that the critical temperature gotten through numerical simulation fits quite well with the theoretical value when there is no external field.

Key words: Ising model, critical temperature, cellular automata
