摘要

A kind of absolutely stable explicit difference schemes with two parameters for the dispersion equation ut＝auxxx are proposed by this paper here.The truncation errors of the schemes are first order in time and second order in space. And the schemes are absolutely stable, simple and easy to calculate. For the present, they are the perfect three level explicit difference schems which have good accuracy, stability and calculation simplity. The numerical examples have examined theresult of theoretical analysis.
