Abstract：
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.
