摘　　要：用时空全离散间断零次有限元对Riemann问题进行了数值求解,没有出现振荡,很好的模拟了稀疏波的逐渐稀疏化和激波的剧烈变化。We apply a discontinuous finite element method of time- space full discretization to compute the Riemann Problem. Our numerical experiments show that there is no oscillation and it simulatcs rarefaction wave and shock wave very well.
