Caudrey-Dodd-Gibbon-Kaeada方程的Hirota双线性形式和多孤子解

Hirota Bilinear form and Multi-Soliton Solutions of CDGK Eequation

通过变换求出Caudrey-Dodd-Gibbon-Kaeada(CDGK)方程的Hirota双线性形式,进而得CDGK出方程多孤子解的解析表达式,并用三维图形展示出CDGK方程多孤子解的主要相互作用过程的特征.

We obtain the Hirota bilinear form of CDGK equation by appropricate transformation, furthery the analytical expressions of multiple-soliton solutions is achieved and the features of the interaction of CDGK equation＇s multiple - soliton solution is illustrated by using the 3D maps.
