摘要
给出一种构造非线性微分差分方程精确解的方法.利用该方法并借助计算机代数系统Maple,获得了一种修正的Volterra链的形式丰富的精确解.该方法也可应用于其他的微分差分方程(组).
An expanded method for constructing nonlinear differential-difference equation is presented. With this method and computer algebra system Maple, many exact solutions of a modified Voherra lattice have been obtained. The method can also be used for other nonlinear differential-difference equations.
