A direct algebraic method to obtain solitary solutions of nonlinear differential-difference equations
求解非线性差分方程孤立波解的直接代数法

In this letter, we extend a direct method for constructing solitary solutions of nonlinear differential-difference equations.Hybrid lattice equations are chosen to illustrate this method.As a result, several solitary solutions are obtained with the help of Maple.This method can also be used in other nonlinear differential-difference equations.
