摘要
基于二维三角晶格模型,分别选取包含7、9个格点自旋的集团为Kadanoff集团,通过实空间重正化群变换分析求解临界点及临界指数,对其结果对比分析表明:选取更大的自旋集团可以提高精度.
Based on the two dimension triangle crystal lattice spin model, we selected groups which contain seven and nine crystal lattices pins as Kadanoff group. The critical point and exponents results which gained by renormalization group transform indicated that Bigger group can increase the precision.
