摘要
采用有限元方法进行空间离散,构造了求一维非线性广义KdV方程孤立波解的五次B样条配置法.数值计算了p=1,p=2和p=3时该方程的孤立波解,从结果来看,它们满足该方程的守恒律.
It made spatial spreading by using the finite element method and constructed the collocation method of quintic B-spline for solving one-dimensio nal nonlinear general KdV equation in this paper. When p=1, p=2 and p=3, the solitary wave solutions of the equation were calculated, which showed that the results met the conservation law of it.
