摘　　要：选取六角形晶格为Kadanoff集团 ,用重正化群方法求得临界点和与之相应的各临界指数 .与三角形晶格重正化群解相比 ,其精度提高了 1 5 %A hexagonal crystal lattice is selected as Kadanoff group, the critical point is found using the method of renormalization group,and its corresponding critical indices is found as well.The precision has increased by 15% as compared with triangular crystal lattice.
