摘要
本文建立了解色散方程的一类新的三层的半显式差分格式 A_4.格式 A_4在很多方面类以于格式 A_3.它们都是无条件稳定的,且都可以显式地进行计算.这两类格式也都可以看作 Du-Fort Frankel 差分格式对色散方程的推广.
A new class of three-level semi-explicit difference schemes A_4 are develpoed in this paper for solving the dispersive equation.Scheme A_4 is similar to scheme A_3 in many ways.They are both unconditionally stable and expli- citly calculated.And both of them can be taken as the generalization of Du-Fort Frankel difference scheme to the dispersive equation.
