| 摘 要： | 用蒙特卡罗重正化群方法计算了二维三角晶格Ising模型的不动点,以及热临界指数和磁临界指数.发现多数法则的重正化群变换得到的不动点远离临界点,临界指数与精确值比较接近.说明多数法则对于求解该问题并不是一个好的变换方法,但是对临界指数的求解没有多大影响.

| Abstract: | This paper discusses the two-dimentional triangular lattice Ising model by using the MCRG,critical temperature and exponents are given.The result shows that the fixed point is far from the critical point of the d=2 Ising model and the exponents are close to the exact values.The fact reveals that the majority rule is not a good transformation in solving this model but has little influence upon the exponents. |
