| 摘 要： | 在Migdal-Kadanoff重整化群变换方案下,我们导出了U(1)格点规范理论的弦张力表式。通过重整化群轨迹的数值计算,我们得到了Callen-Symanzik函数,其结果与连续时空中的微扰论的结果相符。

| Abstract: | In the scheme of Migdal-Kadanoff renormalization group transformation, the etring tension for U(1) lattice gauge theory is discussed. By using of numerical calculation for the Migdal-Kadanoff renormalization trajectories, the Callen-Symanzik function is obtained and can be compared with the result of the perturbation theory in continued space-time. |
