【摘要】 在Ｍｉｇｄａｌ及Ｍｉｇｄａｌ－Ｋａｄａｎｏｆｆ交换方案基础上导出了重整化群方程、并将其应用到Ｗｉｌｓｏｎ形式的Ｕ（１）格点规范理论，给出了强耦合区，弱耦合区及临界耦合点，中间耦合区的数值结果．这些结果与严格的强耦合展开，弱耦合展开及ＭｏｎｔｅＣａｒｌｏ模拟结果一致．从而说明：本文得到的重整化群方程在讨论规范理论的非微扰特性方面是可行而有效的．更多还原

【Abstract】 The renormalization group equation is derived under the scheme of MigdalKadanoff renormalization group transformations.This equation is applied to U(1)lattice group theory.The numerical results for stong and weak coupling regions,including the critical coupling point and the termediate coupling region are presented,which are consistent with the exact results obtained from the strong and weakcoupling expansions and the recent Monte Carlo simulations.更多还原
