组合KdV方程新的Lax表示及其新Bcklund变换

A New Lax Representation and Backlund Transform of the Combination KdV Equation

给出了组合ＫｄＶ方程的一个新的Ｌａｘ表示和用显式表示的自Ｂａｃｋｌｕｎｄ变换，进而导出了它的一类有理解和扭子解。

In this paper,a new Lax representation of the combination KdV equation and itself Backlund transform which can obviously be represented are given.Furthermore,a kind of rational solutions and twisting solutions is obtained.
