英文摘要：

A class of（2＋1）-dimentions disturbed breaking soliton equation was studied via the travelling wave transformation and perturbation theory.Firstly,the corresponding typical breaking equation was considered,and its exact soliton solution was obtained by means of the undetermined constants projectile method.Then,the soliton travelling wave asymptotic solution of a disturbed breaking equation was found by aperturbation method.
