摘要
在这篇论文，扩大 projeetive 途径，最近在一些连续非线性的物理系统被介绍并且成功地使用了，被概括到非线性的部分微分差别的系统(DDE ) 。作为一个具体例子，的准确答案的新家庭(2 + 1 ) 维的 Toda 格子系统被扩大 projeetiveapproach 获得。
In this paper, the extended projective approach, which was recently presented and successfully used in some continuous nonlinear physical systems, is generalized to nonlinear partial differential-difference systems （DDEs）, As a concrete example, new families of exact solutions to the （2＋1）-dimensional Toda lattice system are obtained by the extended projective approach.
