摘要

We investigate the techniques for velocity resonance and apply them to construct soliton molecules using two solitons of the extended Lax equation.What is more,each soliton molecule can be transformed into an asymmetric soliton by changing the parameter φ.In addition,the collision between soliton molecules (or asymmetric soliton) and several soliton solutions is observed.Finally,some related pictures are presented.
