设(G,G+)为一个拟格序群,H为G+的一个可传、定向子集.记GH=G+·H-1,令TGH为相应的Toeplitz算子代数.利用G+的等距协变表示刻画了(G,GH)的顺从性.当G=G+.G+-1时,证明了(G,GH)为顺从当且仅当G为顺从.%Let (G,G+) be a quasi-lattice ordered group, H a directed and hereditary subset of G+. Put GH = G+·H-1, and denote by TGH the corresponding Toeplitz algebra. The amenability of (G, GH) is studied in terms of covariant isometric representations of G+. When G = G+·G+-1, it is proved that (G, GH) is amenable if and only if G is amenable.
