摘要：
A decorated lattice is suggested and the Ising model on it with three kinds of interactions K;,K;,and K;is studied.Using an equivalent transformation,the square decorated Ising lattice is transformed into a regular squareIsing lattice with nearest-neighbor,next-nearest-neighbor,and four-spin interactions,and the critical fixed point is foundat K;=0.5769,K;=-0.0671,and K;=0.3428,which determines the critical temperature of the system.It is alsofound that this system and the regular square Ising lattice,and the eight-vertex model belong to the same universalityclass.
