摘要
改进的哈密顿量对格点（1＋1）维QCD中Wilson费米子真空凝聚<ψψ>做变分研究．结果不但与连续理论的预言值一致，而且几乎不依赖于Wilson参数r．对于改进的哈密顿量而言，么正变换算符中的三链项对<ψψ>
The Wilson fermion Condensates in 1+1 dimensional Lattice QCD are calculated by using the improved Hamiltonian and the variational method.The results are consistant with the predictions from continuum theory,and are almost independent of the Wilson parameter r. The three-links terms give important contribution to<ψψ> in the improved Hamiltonian theory. Received 31 March 1998
