摘要: 考察了混合自旋模型的两种组态按Metropolis动力学随时间的演化,并分析了其在平方格子上的Darnage。计算结果表明存在有一高温相和一低温相,与平衡相变符合。

关键词: 混合自旋模型, Metropolis动力学, Damage Spreading

Abstract: We studied the time evolution of two configurations of the mixed spin model according too metropolis dynamics, and analysed the damage spreading on a square lattice.We found a high temperature phase and a low temperature phase,consistent with equilibrium results.

Key words: mixed spin model, metropolis dynamics, damage spreading
