群

The forces and moments on individual pile are not uniform because of the effects of group piles. The effects of KC number, water depth and current velocity on the coefficient of group piles are discussed.

由于群桩效应使得各组成桩的受力不均匀，通过试验研究，分析了群桩中各组成桩及群桩总体折减系数随KC数的变化、受水深及流速的影响。

The main purpose of this thesis is to study the application of the representation theory in Hochschild homology and cohomology groups of algebras, Hopf algebras and quantum groups, which are very active branches at present.

本学位论文主要研究代数表示论在代数的Hochschild同调群和上同调群，Hopf代数和量子群这几个当今很活跃的数学分支中的应用。

In particular, we compute Hochschild homology and cohomology groups of infinitedimensional path algebras and some of their quotient algebras, and we prove that for a general monomial algebra (not necessary finite-dimensional), all Hochschild cohomology groups of positive degrees vanish if and only if its Gabriel quiver is a finite tree.

特别地，我们计算了无限维路代数以及某些商代数的Hochschild同调群和上同调群，而且给出了一般单项代数的各正次Hochschild上同调群为零的充分必要条件，即它的Gabriel箭图是有限树。

She was now one of a group of oriental beauties who, in the second act of the comic opera, were paraded by the vizier before the new potentate as the treasures of his harem.

The authors find that the commutator growpof this goup is of special character,is it coincides with this matrix.

作者认为这个群的换位子群还具有一个特殊性质──它与这个矩阵群本身重合。

We mainly study the structures of semiring with a completely regular additive semigroup from the angle of semigroups in this paper.

本文主要从半群的角度出发对加法半群为完全正则半群的半环进行了研究。

Because the information in groupware system has Characteristic of complex, various, large quantity, non-structure or structure complex, close relativity of information, etc, and the traditional relational database can hardly handle these complex and various information. This paper aims at the problems that groupware system meets in application, put forward the research on groupware system based on object-oriented database management system.

由于群件系统中所处理的信息具有复杂、多样、量大、非结构化或结构复杂以及信息间的相关性紧密等特征，而传统的关系型数据库很难处理这些复杂多样的信息，因此，本文针对群件系统对数据库的应用需求，提出了基于面向对象数据库管理系统的群件系统的研究。

The participants were fifth grade students and they were divided into high score group, middle score group, and low score group according to their achievement in the learning area of science and technology. There were two learning projects in two periods of experimental instruction with different participants: the first project was concave and convex lens and the second project was the investigation of sound and create instrument.

研究对象为国小五年级学生，以学生的自然与生活科技学习成就，将学生分为高分群、中分群、低分群，进行不同研究对象的二阶段实验教学，其学习主题：第一阶段为「凹透镜与凸透镜」，第二阶段为「声音的探讨与乐器制作」。

At the same time, some properties of rough Set in quotient ring are given and proved. The fifth chapter is Rough Primary Ideals and Rough Fuzzy Primary Ideals in Semigroups, the concept of rough primary ideals and fuzzy rough primary ideals in semigroups are introduced. Under the condition of the complete congruence relation, a rough set of a primary ideal in semigroups is proved to be its primary ideal.

同时，在商环中讨论了粗糙集的一些性质，并给出这些结论的严格证明；第五章是半群中的粗准素理想和粗模糊准素理想，首次提出了半群中的粗准素理想与粗模糊准素理想的概念，证明了在完备同余关系下，半群中准素理想的粗糙集是准素理想。

The shape of their conidiospore is round, spindly, bacilliform, and so on.

各菌落出现的次数不仅在不同居群不同杜鹃根系中很不平衡，即使在同种不同居群内差别也很大，褐黄杜鹃和其他居群其他种共有的菌较少。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
