把离散的Lie点对称群分析方法应用于(1+1)维非线性微分-差分Toda-like方程,即首先引入条件对称,之后解相应的超定方程组,进而对该方程进行了相似约化,得到了方程的新的精确解。
把離散的Lie點對稱群分析方法應用于(1+1)維非線性微分-差分Toda-like方程,即首先引入條件對稱,之後解相應的超定方程組,進而對該方程進行瞭相似約化,得到瞭方程的新的精確解。

In this paper , the discrete Lie point symmetry group analysis method is applied on the ( 1+1 ) dimensional nonlinear differential -difference Toda-like equation, i.e.firstly, the conditional symmetries is in-troduced, after that the overdetermined equations are solved , and then similarity reduction for the equation is done , and the new exact solutions of this equation are obtained .
