%X The elliptic boundary value problems are investigated on polygonal domains.Some wei-ghted a priori estimates are obtained.Furthermore,a class of triangulations with local refine-ment is introduced and a class of special.FE spaces we constructed to obtain optimal errorestimates.All the computation of the FE equation are reduced to the case of a standard FEMsuitablt for vector computers.
