论述了自洽集团方法(SCM)与修正集团场方法(MCFM)的等价性,在SCM和MCFM的基础上,提出了一种计算临界点的新方案,并以正方格子Ising模型为例介绍这种方案的应用We show the equivalence between the self-consistent cluster method (SCM) and the modified cluster field method (MCFM). Based on the SCM and MCFM, we propose a new method to- calculate critical points of Ising spin system, the method is demonstrated on the two-dimension square lattice.
