摘要
对tanh函数方法进行了对称延拓 ,并拓广了它的应用范围 ,将其应用于非线性离散系统的求解 .研究了Hybrid Lattice系统和Ablowitz Ladik Lattice系统 .
In this paper, by using the improved tanh-method, the hybrid-lattice system and Ablowitz-ladik-lattice system are reduced to nonlinear algebraic equations, and then the new exact solutions for these equations, which include exact soliton wave solutions and periodic solutions, are obtained through solving these nonlinear algebraic equations.
