摘　　要：用改进的格点规范场哈密顿量和截断本征方程法计算2+1维U(1)规范场的0++胶球波函数,三阶结果比二阶结果的标度行为有了较大的改善.Using the improved lattice gauge field Hamiltonian and the truncated eigenvalue equation method, we compute the 0++ glueball wave function in the three-dimensional U(1) lattice gauge theory up to the 3rd order. The scaling behavior of the 3rd order result is much better than that of the 2nd order result.
