KdV方程的左行孤子解及其相互作用

THE SOLITON SOLUTIONS OF KdV EQUATION RUNNING TO THE LEFT AND THEIR INTERACTIONS

本文指出,KdV方程允许存在左行孤子、静态孤子和左、右行孤子的相互作用解。左行孤子的振幅越大,运动得越慢。

We point out that there exist the soliton solutions of the KdV equation running to the left, as well as static and the interaction solutions between left running and right running solitons. The larger the amplitude of the left running soliton is, the slower it moves.
