| 摘 要： | 利用改进的双曲函数法，研究离散的非线性薛定谔方程，不仅得到了离散暗孤子解，还获得了离散亮孤子解以及其它一些新形式的离散类孤子解。这种方法也同样适用于求解其它离散的非线性波方程。

| Abstract: | With the help of the further improved hyperbolic functions method, the new discrete soliton solutions for the discrete nonlinear Schrodinger equation are obtained,which include discrete kink-type soliton solution, bell-type soliton solution and new formal soliton-like solutions. It indicates that the method is also suitable for solving other discrete nonlinear evolution equations. |
