In this paper,a new finite element method,discontinuous finite difference streamline diffusion method is studied for first-order linear hyperbolic problems.A discontinuity-type explicit finite element scheme with artificial diffusion parameter is constructed,the stability and convergence in proper norm are established for the considered scheme.Finally,a numerical example is provided to show the highly efficiency of the new scheme.
