摘要：
The mixed Chen-Lee-Liu derivative nonlinear Schrodinger equation (CLL-NLS) is studied in this paper. From the zero seed solution, the determinant expression of the n-soliton solution of the CLL-NLS equation is obtained, and the positon solution is constructed by means of the degenerate Darboux transform. Furthermore, the modular square of the positon solution is decomposed to obtain the approximate trajectory and "phase shift", and then its dynamic properties are studied. The mixed solutions of positon and soliton are also derived, and their dynamic evolution diagrams are studied.
