在齐次平衡法、试探函数法的基础上,给出指数函数所组成的两种试探函数法,并借助符号计算系统Mathematica构造了Hybrid-Lattice系统、mKdV差分微分方程、Ablowitz-Ladik-Lattice系统等非线性离散系统的新的精确孤波解.
Based on the homogeneous balance method and trial function method,two trial func- tion methods of exponential functions are presented.New exact solitary solutions to the nonlinear discrete systems are constructed by use of these methods and with the help of symbolic computa- tion system Mathematica,such as the discrete Hybrid-Lattice system,mKdV differential-difference equations,Ablowitz-Ladik-Lattice system.
