本文用Monte Carlo方法对四维对称格点规范理论中具有较好标度性行为的单元格EXP作用量计算了重夸克-反夸克势。计算中利用了重整化群处理方法和SU(2)群的正二十面体子群近似。计算结果与维象的弦理论给出的库仑势加线性势的形式一致。The heavy quark-antiquark force and potential are calculated by means of Monte Carlo method in 4 dimensional symmetry lattice gauge theory for a single plaquette EXP action which has a good scaling behaviour. The renormalization group treatment and the icosahedral subgroup approximation to SU(2) are used. The resultes agreet with Coulomb plus linear form obtained from phenomenological string theories.
