摘要

We construct the soliton solution and smooth positon solution of the second-type derivative nonlinear Schr（o）dinger (DNLSII) equation.Additionally,we present a detailed discussion about the decomposition of the positon solution,and display its approximate orbits and variable "phase shift".The second and third order breather-positon solutions are also constructed.
