摘要： This paper is devoted to studying the superconvergence of streamline diffusion finite element methods for convection-diffusion problems.In [8], under the condition that ε≤h2 the optimal finite element error estimate was obtained in L2-norm.In the present paper,however,the same error estimate result is gained under the weaker condition that ε≤h.
