本文得到了Hirota-Ramani（HR）方程和Drinfel 'd-Sokolov-Wilson（DSW）系统的Lie对称群的微分不变量，并对它们的syzyry和递推关系进行了分类.该算法基于等变移动标架方法。
In this paper, the differential invariants of Lie symmetry groups of Hirota–Ramani (HR) equation and Drinfel’d–Sokolov–Wilson (DSW) system are obtained and their syzygies and recurrence relations are classified. The algorithms are based on the method of equivariant moving frames.
