摘要
本文首先总结了文献[1─4]提出的形式级数对称理论在高维可积模型的研究中所取得的科研成果，然后，将其推广应用到（2+1）维的离散型Toda方程，得到了二族四个广义截断对称。
This papre summarizes achievements of the formal series symmetry theory which was proposed in references (l─4) in higher-dimensional integrable model.Then the method is extended to (2+1) dimensiana discrete Toda eguation.I found two sets of four trancated generalized symmetries.
