| 1. | Some characteristics of ring theory andgraph theory on finite group automata 有限群自动机的若干环论与图论性质 |
| 2. | An evaluation of current state in systems enginee ring theory amp; amp; practice 近年来我国系统工程理论与实践的研究及进展 |
| 3. | Since then , the theory of morita duality has become one of the important fields of ring theory and module theory Morita对偶理论起源于数域上的向量空间的对偶空间理论。 |
| 4. | C . menini and a . d . rio introduced a graded morita duality into graded ring theory and obtained the similar characterizations of the morita duality Rio在分次环中引入分次morita对偶的概念,得到了与morita对偶相类似的刻划。 |
| 5. | V - ring is an important conception of ring theory , many mathematic authors all the world have made extensive discussion on v - rings . as generalization , main aim of this paper are to discuss regularities or strongly regularities of gp - v - ring , gp - v - ring and spf - ring 作为v -环的推广,本文的主要目的是讨论gp - v -环, gp - v -环与spf -环的正则性或强正则性。 |
| 6. | In the past , there are three main methods used to calculating the deformation of the ring of mechanica1 sea1 . 0ne is the method based on germma ' s ring theory , the other one is based on becheno ' s ring theory ; the third is the finite e1ement method 过去,密封环力变形的计算方法主要有三种:一是基于盖马圆环理论的方法;第二是基于皮采诺圆环理论的方法;第三是有限元法。 |
| 7. | In the last section , we discuss the covers and envelopes both of which are of great importance in the field of ring theories . by the morita context functors we can transform from rx - cover ( envelope ) into sx - f - cover ( envelope ) . finally they are further characterized by the particular properties of the direct limit 在第四部分中,我们对环论中十分重要的内容? ?包与盖进行探讨,通过一类特殊的模范畴_ rx ( _ sx ) ,使_ rx -包(盖)在moritacontext函子作用下转化为_ sx -包(盖) ,最后利用正向极限的特性,进一步刻画这类特殊的包与盖。 |
