Then we deeply studied the completeness of LP . Consequently, we established:(1) The completeness theorem of LP with truth-value in finite Lukasiewiczchain;(2) The completeness theorem of LP with truth-value in complete and atomic lattice implication algebras;(3) The completeness theorem of LP with truth-value in injective lattice implication algebras.

建立了：（1）基于Lukasiewicz有限链的格值命题逻辑系统LP的完备性定理；（2）基于完备的且原子的格蕴涵代数的格值命题逻辑系统LP的完备性定理；（3）基于内射的格蕴涵代数的格值命题逻辑系统LP的完备性定理。

Next, we discuss the relations between left quasi-dual bimodules and left dual-bimodules, we obtain that a left quasi-dual bimodule is a left dual bimodule if it satisfies one of the following conditions: sM is minimal injective and MR is a M-minimal injective kasch-module; MR is a M-minimal injective kasch-module and for any two ideals LI and L2 ofSS rM(L1 n L2)-rw(L1)+rM(I2); sM is minimal injective and for any two submodules A and B of MR,Lastly, we applicate the quasi-duality on smash product algebra R#H, and obtain an answer of the semiprime problem, i.e., let H be a finite-dimensional semisimple Hopf algebra and R be an H-module algebra, if R is left quasi-dual and semiprime, then R#H is semiprime.

我们得到：一个左拟对偶双边模如果满足下列条件之一，则它将成为一个左对偶双边模：_sM是单内射的并且M_R是一个M-单内射kasch-模；M_R是一个M-单内射kasch-模并且对_sS的任意两个理想，有r_M(L_1∩L_2)=r_M(L_1)+r_M(L_2)；_sM是单内射的且对M_R的任意两个子模，有l_s=l_s+l_s。2 在第2.3节中我们将拟对偶性应用于smash积代数R#H，部分解决了半素问题。

Due to the inspiration of maximal injective module by professor Wang Ming-yi, in chapter two, we introduce the conception of max-projective modules, discuss its properties, applications: the primitive relations between rings and endomorphism rings, an equivalence that is surrounding strongly V.N. rings.

受汪明义教授引进极大内射模概念的启发，在第二章中我们引进了极大投射模的概念，由此讨论了它的一些性质及其应用：环与自同态环之间的本原性关系；强正则环的一个等价刻划；并在环为交换和非交换的情形下分别应用有限表现模的极大投射性得出了SF环和Von Neumann正则环的关系。

The injectivity of a Clifford semigroup and its ideals is investigated,and the homological classification of a Clifford semigroup by the injective properties over its ideals is gained.

Empty pee is discharged first before massaging, intercrop of husband and wife caresses a movement, in caress the foundation that causes sexual excitement adequately to go up, place common massager again upper part or perineal ministry are combined in pubic bones, open massager switch comes slow archives, increase gradually later, till in grain is exciting, massage 10-15 every time minute, reach certain level when sexual pleasure, when be about to ejaculate, stop to massage namely, have sexual intercourse instantly, if make love for some time to still do not have ejaculation feeling, the reentry when undertaking massage coming be about to ejaculating again makes love all right, make seminal fluid is shot as far as possible inside the vagina.

按摩前先排空小便，夫妻间作爱抚动作，在充分爱抚引起性兴奋的基础上，再将普通按摩器放置在耻骨联合上方或会阴部，开启按摩器开关至慢档，以后逐渐增大，直至中小量刺激，每次按摩10%26mdash；15分钟，当性快感达到一定程度，快要射精时即停止按摩，立即进行性交，如性交一段时间仍无射精感，再进行按摩至欲射精时再进行性交，尽可能使精液射在阴道内。

Ran AV industry is highly competitive, in order to stimulate buying, most of them have to live ammunition, and even whether the sets of sexual intercourse and intravaginal ejaculation picture.

然现在AV界竞争激烈，为激励买气，大多得真枪实弹上场，甚至有无套性交和阴道内射精的画面。

The first chapter, main instead " duo-ring " condition of " every maximal left ideal is GW-ideal " condition,study strongly regularities of GP-V-ring on this condition.lt is shown that (1) R is strongly regular iff R is left GP-V-ring whose maximal left ideals are GW-ideal.(2)R is strongly regular iff R is left GP-V-ring whose maximal right ideals are GW-ideal. The second chapter, generalize some results of GP-V-ring to GP-V-ring, discuss regularity of GP-V-ring.It is shown that (1) R is left self-injective regular with non-zero socle iff R is left GP-V -ring with Soc = Soc and R contains an injective maximal left ideal.(2)R is regular ring and every maximal essential left ideal is ideal iff R is left GP-injective left GP-V -ring and every maximal essential left ideal is ideal.

第一章主要将"duo-环"条件替换成"每一极大左理想是GW-理想"条件，研究在此条件下，GP-V-环的强正则性，证明了：(1)R是强正则环当且仅当R是左GP-V-环且R的每一极大左理想是广义弱理想；(2)R是强正则环当且仅当R是左GP-V-环且R的每一极大右理想是广义弱理想，第二章，主要将GP-V-环上一些结果推广到GP-V′-环上，讨论GP-V′-环的正则性，证明了：(1)R是左自内射正则环且Soc≠0当且仅当R是包含内射极大左理想的GP-V′-环，且Soc=Soc；(2)R是正则环且每一极大本质左理想是理想当且仅当R是左GP-内射的左GP-V′-环且每一极大本质左理想是理想。

Firstly, the regularity of right nonsingular AGP-injective rings are studied.

首先，研究了非奇异的AGP-内射环的正则性。

A separable functor F:〓M→〓M has more properties: information about semisimplicity, injectivity, and projectivity of objects in 〓M yields information about the corresponding properties in 〓M.

并且当F：〓M→〓M是可分函子时，如果范畴〓M中的对象具有半单性、内射性、投射性，那么在范畴〓M中的相应对象将仍然保持这些性质。
