群

It is important to study the structures of finite groups by combining some subgroups with some properties in the researches on finite groups.

用有限群的子群研究有限群的结构在有限群的研究中有重要的作用。

After analyzing disadvantages of artificial fish-swarm algorithm and particle swarm optimization algorithm, this paper presents a hybrid algorithm. In the algorithm, AFSA and PSO are regarded as two independent swarms to search in the synchronical way.

在分析人工鱼群算法、粒子群算法存在不足的基础上，提出一种将PSO群与AFSA群作为两个独立进化的群，同时进行搜索的算法。

In chapter two of this paper, we introduce the transitivity, which is an important definition in the 1-permutation group.

在第三章，我们介绍了格序置换群的凸同余，并研究了可迁格序置换群的凸同余与块所决定的可迁格序置换群的分类；讨论了可迁格序置换群的凸同余和块的性质以及它们之间的关系。

However, upper airway obstruction is encountered after palatoplasty with certain craniofacial abnormalities (e.g., Treacher Collins syndrome, Turner's syndrome, Pierre-Robin syndrome, and Down's syndrome, etc.).

上呼吸道阻塞会在颚修补术后，一些特定颅颜畸型的病人发生（如Treacher Collin症侯群、Turner's症侯群、Pierre-Sequence症侯群、Down症侯群等）。

Finally, the article brings forward policy suggestions on how to support and develop the local clusters of enterprises and strengthen the regional economy strength standing on the side of government, and countermeasure used to foster well environment of cluster development, build well unisonous competition mechanism, advance the competitive of the enterprises in the clusters.

最后，论文基于上述研究思路和结论，提出了政府扶持发展地方特色企业集群、增强地区经济实力的政策性建议；以及集群内企业与地方政府一道为培育良好的集群发展环境、建设良好的协调竞争机制、以提升集群内企业竞争力的对策。

The classical group theory is an important research branch of group theory, and Unitary group is one kind of such important classical group.

典型群理论是群理论的重要组成部分，酉群是一类重要的典型群。

Wehave obtained two formulas to express thire relation in different view;at the same time,wegive an explicit description of multiplicative unitary operators corresponding to compactquantum group 〓 and 〓 on concrete Hilbert spaces.

我们首先在第四章讨论了紧量子群对应的乘法酉算子和紧量子群与离散群的交叉积对应乘法酉算子的关系，我们得到了在不同观点下的它们之间的关系式；同时给出了紧量子群〓对应的乘法酉算子和〓对应的乘法酉算子在具体的Hilbert空间上它们之间的表达式。

The main results are as follows.(1) Suppose that K is abelian and every Sylow subgrop S of K has a complement in a Sylow subgroup of G which contains S.

主要结果如下：(1)假设K是Abel群并且K的每个Sylow子群S在G之含S的Sylow子群中有补子群。

In chapter 2, we investigate the structure of finite groups under the condition that all special subgroups are conjugate-permutable subgroups and obtain some sufficient conditions for solvability, Abelian property of finite groups.

第二章主要是利用一些特殊子群的共轭置换性得到了有限群成为可解群、交换群的一些充分条件，改进和推广了文[1]和[4]中的部分结果，有些结果是新的。

In order to investigate patterns of phenotypic trait variation in natural populations of Amygdalus ledebouriana, we measured eight morphological traits in five A. ledebouriana populations in Xinjiang.

为了从数量上分析新疆野扁桃天然居群表型性状在居群间和居群内的变异，我们于2007年对分布在新疆的5个野扁桃天然居群的8个表型性状进行了测量和比较分析。

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。
