摘要：

In this paper, we construct a projection interpolation for cubic triangular element by using othogonal expansion triangular method. We show two fundamental formulas of estimation on a special partion and obtain a superconvergence result of 1 - epsilon order higher for the placement function and its tangential derivative on the third order Lobatto points and Gauss points on each edge of triangular element.
