摘要：

For a discontinuous Toda medium, a differential-difference equation(DDE) can be established. A modification of the exp-function method is applied to construct some soliton-like and period-like solutions for nonlinear DDEs with variable coefficients. The solution process is simple and straightforward and some new solutions are obtained with full physical understanding.
