  2. E. e. enochs put forword the concepts of injective ( projective or flat ) ( pre ) cover and ( pre ) envelope in the early 1980s ", a lot of articles have studied existence and uniqueness of such ( pre ) covers and ( pre ) envelopes, the property of their kernels or cokernels, and character many special rings. moreover, if such kind of ( pre ) covers or ( pre ) envelopes exist, we can construct a complete injective ( projective or flat ) resolvent ( called resolution when exact ) and a partial injective ( projective or flat ) resolvent, and if r is a ring, we can study the relationship of its left global dimension l. d ( r ) ( or its weak dimension w ( r ) ) and the properties of syzygies ( or cosyzygies ) of a resolvent ( or resolution ), and the relationship of its left global dimension l. d ( r ) ( or its weak dimension ) and the exactness of a resolvent ( or resolution )

    自八十年代初e . e . enochs首次提出並研究內射(投射、平坦) (預)蓋及內射(投射、平坦) (預)包這些概念以來,大批論文研究此類包、蓋的存在性、唯一性問題以及它們的核、上核的性質,並據此刻畫了一些常見的特殊環;更進一步地,當此類包、蓋存在時,我們可構造相應的完全投射(平坦、內射)預解式(當正合時稱為完全分解式)以及單邊投射(平坦、內射)預解式,研究了環的左(右)總體維數、弱維數與此類分解式的合沖模(或上合沖模)的性質、復形正合性之間的關系。
  3. In the second section, the author studies copure injective modules, which are the kernels of injective precovers. at first the author gives some characterizations of copure injective modules, show many characterizations of reduced copure injective modules, and then study when injective precover is exact. moreover, the author claims that if l. pid ( r ) of a ring is finite, some copure injective modules can be obtained by a resolvent, finally analyze the relationship between syzygies of a resolvent and cosyzygies of a resolution on n - gorenstein rings

  4. In this thesis, we will discuss the homological dimension and homological properities of rings and modules which is one of the most impertinent parts in homological theory. in the first chapter, we investigate the relation of homological properities between ring r. [ [ x ] ] and ring r, we prove that a module m is an injective or a flat r - module, then it is an injective or a flat r [ [ x ] ] - module respectively, and if m is an injective or a flat r - module, then hom ( r [ [ x ] ], m ) is an injective r [ [ x ) ] - module, r. [ [ x } ] m is a flat r { [ x ] } - module

    在第一章中,我們主要研究了冪級數環r [ [ x ] ]與環r上的模的平坦性與內射性之間的關系。證明了當只是一個完全凝聚交換環時,如果m是一個內射或平坦r [ x ] -模,則m是一個內射或平坦r -模。如果m是一個平坦r -模,則r [ x ] _ rm是一個平坦r [ x ] -模。
