关于扭类B_n与B_w的几点注记

On Some Notes of the Torsion Classes B_n and B_w

本文研究扭类B_n与B_w的性质，改进文献[1]中的部分结果．与此同时，在非可换的条件下，建立了紧生成l－群等价的又一个充要条件．

：Some properties on the torsion classes B_n and B_w in this paper are studied and results in paper [1] are so improved． At the same time， a sufficience and necessity of the equivalence of compactly generated l－groups is set up under non－Abelian condition．
