摘　　要：本文主要采用首次积分法对广义带导数的非线性Schrodinger方程进行研究,通过引入行波变换化简方程,将原广义带导数的非线性Schrodinger方程转化为常微分方程,再根据多项式的整除定理,得到广义带导数的非线性Schrodinger方程的精确行波解。The first integral method is mainly adopted in this paper to study the nonlinear generalized Schrodinger equation with derivative. By introducing the traveling wave transformation, the original nonlinear generalized Schrodinger equation with derivative has been changed into an ordinary differential equation. Then according to the division theorem of polynomial, exact traveling wave solutions of the nonlinear generalized Schrodinger equation with derivative are obtained.
