利用一个投射方程和变量分离法,得到了(2+1)维Korteweg-de Vries(KdV)方程的新显式精确解.根据得到的孤立波解,构造出KdV方程的传播孤子结构.利用一个新的混沌系统研究了孤子的混沌行为。
With a projective equation and a linear variable separation method,new exact solutions of the(2 + 1)-dimensional Korteweg-de Vries system(KdV) is derived.Based on the derived solitary wave excitation,we obtain the propagating solitons and study the chaotic behaviours with a new chaotic system.
