摘要 主要利用直接截断法,结合了Riccati射影方程的解讨论非线性高次薛定谔方程:iut+uxx+a0|u|2u+i[γ1uxx+γ2|u|2ux+γ3(|u|2)xu]=0(1)的精确解.得到了非线性高次薛定谔方程一些新的精确解. Mainly by the direct truncation method and the solutions of projective Riccati equations, this paper discuss new exact solutions of the higher order nonlinear Schrtidinger equation:iut+uxx+a0|u|^2u+i[γ1uxx+γ2|u|^2ux+γ3(|u|^2xu]=0 ( 1 ) with the help of symbolic computation system Maple, this paper derive some new exact solutions of the higher order nonlinear Schr? dinger equation.
