摘要
A newly revised inverse scattering transform（IST） is used to solve the derivative nonlinear Schr？dinger（DNLS-＋） equation with non-vanishing boundary condition（NVBC） and normal group-velocity dispersion, and a mixed type of soliton solution is found, which is composed of both pure and breather-type solitons. The mixed-soliton solution can degenerate into breathers and pure solitons when taking the limit of some special parameters, proving the validity of the mixed-type solution.
