Introduce the corresponding concepts of cover and hull through Q gets the properties of τ-injective,τ-projective,τ-divisible and τ-codivisible,discuss the properties of τ-torsion injective hull, τ-torsion projective cover,τ-torsionfree divisible hull and τ-torsionfree codivisible cover, τ-injective hull E_τ(M) is characterized by using them.

5) direct-projective covers
直投射覆盖
1.
This peper introduces the concept of direct-projective covers,and prove that a ring R is left perfect if and only if every left R-module(flat left R-module) has a direct-projective cover;if and only if a direct limit of(finitely generated) quasi-projective R-modules is direct-projective.
本文引入直投射覆盖的概念，证明了环Ｒ为左完全环当且仅当每一个左Ｒ－模（平坦左Ｒ－模）具有直投射覆盖；当且仅当（有限生成）拟投射左Ｒ－模的直极限为直投射模。
6) τ-weak projective cover

1.
In the paper, we describe when τ-weak projective modules are closed under taking homomorphic images, which is dual to τ-injective module; we also describe a distinguish theorem on τ-weak projective cover.
本文给出了与τ-内射模对偶的一类模,称为τ-弱投射模,关于商模封闭的条件;同时描述了τ-投射盖的概念,给出了关于τ-弱投射盖的一个判别定理。
补充资料：盖天盖地
【盖天盖地】
（杂语）覆盖天地也。又曰普天普地。示自己意气满溢，磅礴于宇宙之意。宗门统要续集十六岩头全斋条所谓：“师云：若欲播扬大教，一一从自己胸襟流出将来，为我盖天盖地去”之类是也。
