摘　　要：We present a rational solution for a mixed nonlinear Schr6dinger （MNLS） equation. This solution has two free parameters, a and b, representing the contributions of self-steepening and self phase-modulation （SPM） of an associated physical system, respectively. It describes five soliton states： a paired bright-bright soliton, a single soliton, a paired bright-grey soliton, a paired bright-black soliton, and a rogue wave state. We show that the transition among these live states is induced by self-steepening and SPM through tuning the values of a and b. This is a unique and potentially fundamentally important phenomenon in a physical system described by the MNLS eauation.We present a rational solution for a mixed nonlinear Schr6dinger （MNLS） equation.
