摘要
本文利用李代数在矢量场的实现，得到了具有相似群不变的一般的k阶微分方程,同时许多熟知的1＋1微的可积模型如kdv方程等也被给出。
This papers is deroted to the most general k-th order differential equation invariant under simeitude group by ineans of a realization of the algebra by vector. Many well-Known 1＋1 dimensional integrable models such as kdy equation are given too.
