摘要: 通过引入变换和选准试探函数,把难于求解的非线性偏微分方程化为易于求解的代数方程,然后用待定系数法确定相应的常数,从而简洁地求得了非线性薛定谔方程的解析解.

Abstract: By introducing transformation and selecting appropriate trial functions, the nonlinear partial differential equation that is hard to be solved by the usual way is reduced to a set of algebraic equations, which can be easily solved, and their related coefficients can be easily determined by the undetermined coefficient method. Finally, the analytical solutions to nonlinear Schrodinger equation are successfully derived.

Key words: trial function method, nonlinear Schrodinger equation, analytical Solution
