摘要：
In this work, a fifth-order nonlinear Schrodinger equation with variable coefficients is in-vestigated, which represents the diffusion of ultrashort pulses in incompatible optical fibers. With the aid of two direct functions, some non-traveling wave bright and dark soliton solutions are obtained. Via the G '/G-expansion method, the non-traveling wave hyperbolic -type and trigonometric-type solutions are studied. Finally, we show the dynamic properties and characteristics of these derived results by using some three-dimensional figures and contour figures.
