Abstract
The Wilson fermion Condensates in 1+1 dimensional Lattice QCD are calculate d 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 [<(psi)over bar>psi] in the improved Hamiltonian theory.
