摘　　要：采用位置空间重整化群方法,对简立方格子(SC)键渗流模型进行了研究,得到了临界值pc、模型在相变点的分形维数D和临界指数γ.所得结果与文献值大体一致.The renormalization group approach is used to treat the problem of bond percolation on simple cubic lattice. The threshold p_c, the fractal dimension D and the critical exponent γ are obtained. The results basically agree with known results.
