摘要
New breather solitary solution and two-solitary solutions depending on constant equilibrium solution to the Korteweg de Vries equation are obtained by using an extended homoclinic test approach.A new mechanical feature of a two-solitary wave,namely,dependence of propagation direction and shape on position of equilibrium point,is investigated.
