| 摘 要： | 在SG分形晶格上研究二体自旋作用和三体自旋作用都存在时Gauss模型的相变和临界性质，与只有二体自旋作用的情况相比较，在无外场和有外场的情况下，临界点和临界指数都发生了变化，这表明三体自旋作用对其临界点和临界性质都有一定的影响．

| Abstract: | Phase transition and critical property of Gauss model are discussed on the SG fractal lattice when disome spinning and trisome spinning exist togeuher.Comparing with only disome spinning existing,the critical point and critical exponent are all changed in both no external field and external field.It is shown that trisome spinning has some influence on it's critical point and critical property. |
