摘要：
A basis for the quadratic (P-2) nonconforming element of Fortin and Soulie on triangles is introduced. The local and global interpolation operators are defined. Error estimates of optimal order are derived in both broken energy and L-2(Omega)-norms for second-order elliptic problems. Brief numerical results are also shown.
