In the second chapter, we study the regularity of SF-rings whose every maximal essential one-sided ideal is generalized weak ideal.
第二章，主要研究极大本质单边理想是广义弱理想的SF -环的正则性。

A class of solvable 3-lie algebras with a 5-dimensional maximal hypo-nilpotent ideal, which is a 5-dimensional simplest filiform 3-lie algebra, is constructed.
We study the regularity of right SF-rings whose every maximal right ideal is a quasi-ideal. Some new characterizations on the regularity of right SF-rings are obtained, which generalize some results.
