%X In this paper, based on a new mixed variational form for second order elliptic problem, we present some new solving schemes of any order which satisfy strongly elliptic condition and B-B condition. Theory analysis show that these schemes are simple and convenient. Moreover, we obtain optimal error estimates on the anisotropic meshes.
