摘　　要：应用等效变换的方法,把镶嵌正方格子铁磁Ising模型转化为可求解的正方格子。采用重整化群变换,得到了正方格子上Ising模型的临界点。通过得到的两个变换关系,求得镶嵌正方晶格上Ising模型的临界点为K*=0.405。Using the equivalent transformation technique, the ferromagnet Ising model on square decorated lattice is translated into the solvable square lattice. Then according to the renormalization group （RG）, it deduces the critical point K^＊ = 0.405 of Ising model on square lattice. Combining two recursion relations obtained in this paper, the critical point of Ising model on square decorated lattice is given.
