%X Two classes of superconvergence points forL 2-projection un inn-degree finite elements on uniform grids are shown by element analysis method. Superconvergence points ofu n aren + 1 order Gauss point Gn+1 for oddd -1 (so the endpoint of each element is of superconvergent), andn + 1 order pointset Zn+1 for even n≥2 (which includes the endpoints and midpoint), respectively. Symmetry point is only an important part of them.
