摘　　要：本文给出了非线性双曲型方程数值积分下的全离散有限元解法。数值积分公式的特别选取为最终求解提供了方便。文中给出了格式的稳定性和误差分析,获得与文[1]相同的误差阶。In this paper, we study the total discrete finite element method under numerical integration for the nonlinear hyperbolic equations with the first boundary conditions. The solution is made much easier under the extra choice for numerical integration.We discuss the stability to the calculating form and error estimates and obtain the same order as paper[1].
