摘　　要：应用位置空间重整化群方法,采用单向“导通”规则和三向入“鬼”方式,对引入“鬼”场的三维简立方格子点渗流模型进行了研究,得到了临界值 和临界指数 , , , , , .最后提出:可采用各种“导通”规则和入“鬼”方式讨论立方格子渗流模型.Onthebaseof thesingledirectionconductionandthreedirections reaching'ghost', therealposition-space renormalization group approach is used to treat the problem of percolation on a three-dimension simple cubic lattice with 'ghost' field. The percolation threshold and the critical exponents , , , , , are obtained. Study cubic lattice on varieties of conduction rule and reaching 'ghost' rule was suggested in the end.
