查询词典 generated group

Metacyclic group, which is the expansion of a cyclic group by a cyclic group, is a special group generated by two elements.

亚循环群，即循环群被循环群的扩张，是特殊的二元生成群，Otto Hlder曾研究并给出了有限亚循环群的构造；G。

A group is '''finitely generated'''(respectively '''finitely related''','''finitely presented''') if it has a presentation that is finitely generated (respectively finitely related, a finite presentation).

群是'''有限生成'''的(分别为'''有限关联'''的，'''有限展现'''的)，如果它有有限生成的(分别为有限关联的，有限展示的)的展示。

Not every subgroup of a D-group is also a D-group. If a subgroup is a D-group we call the subgroup "sub- D -group." The "commutator ideal" of G is the smallest sub-D-group containing its commutator subgroup. We found that the commutator ideal can be viewed as a finitely generated module over a ring when G is a finitely generated metabelian D-group.

并非每个子群都是一个可除群，若一个子群是可除群，我们称之为子可除群(sub-D-group)，而G 的交换子理想则是在G中包含其导出群的最小子可除群，我们发现当G是一个有限生成亚交换可除群时，其交换子理想是一个有限生成模。

The four fluorescence peaks are generated separately by the combined actions of the methyl parathion and the acetone. In methyl parathion molecule, there are the transition of n electrons in nitryl, the transition of π electronic structure formed by the oxygen atom and the benzene ring and the transition of n electrons in P=O group. In acetone molecule, there is the transition of n electrons in C=O group.

分析得到，四处荧光峰分别是溶剂丙酮分子中C=O上的n电子跃迁、硝基上的n电子跃迁、甲基对硫磷分子中氧原子与苯环形成的大共轭π电子结构跃迁以及P=S上的n电子跃迁共同作用产生。

Methods The study was carried out in laboratory and field in Guangzhou from September to November in 2007. The Mosq-ovitrap in tested group with yeast-generated CO2, Panicum maximum infusion, tyre infusion, L-lactic acid dilution, or darken surface and that in control group with tap water were set at intervals of 20 cm, respectively.

研究在实验室和现场分别进行，实验组诱蚊诱卵器中分别添加酵母发酵产生的CO2、大黍叶浸出液、轮胎浸出液、乳酸稀释液以及改变杯身的颜色，对照组加过夜自来水，布放5 d，计算捕获的白纹伊蚊数量和产卵的数量。

The method for constructing LDPCC code includes encoder and decoder. Operational steps include as following: determining parameters of checkout matrix HQT of group code of permutation unit matrix LDPC; constructing checkout matrix HQT of group code of permutation unit matrix LDPC; constructing checkout polynomial matrix HT of LDPCC code; exporting generated matrix G of LDPCC code.

一种LDPCC码的构造方法，包括编、译码器，运行的步骤包括：初始化的步骤；确定一个置换单位矩阵LDPC分组码的校验阵HQT的参数的步骤；构造置换单位矩阵LDPC码校验阵HQT的步骤；构造LDPCC码的校验多项式矩阵HT的步骤；导出LDPCC码的生成矩阵G的步骤。

In the detecting of humoral immunity, cell immunity and mucosal immunity. The immuneresponse level of advanced immunization group and normal immunization group are all higher thancontrol group. It certify the immune response is specific and generated with swine plague vaccinemotivation.

4在体液免疫、细胞免疫和黏膜免疫检测中，超免组和普免组的免疫应答水平均高于对照组，说明均为猪瘟疫苗所产生的特异性免疫应答，而且三种检测方法的动态规律基本一致。

ABSTRACT: Random amplified polymorphic DNA was used in analysing the relationship among twenty-six speices of Amanita from Mangshan, Hunan. Of 40 primers, 6 ones generated reproducible RAPD profiles, and each one produced 1-10 bands. Two primers (OPG15 and OPH04) could differentiate 26 species of Amanita by its RAPD profiles. The similarity coefficients obtained from profiles generated by six primers among Amanita were about 20-60%. A dendrogram was constructed using average linkage clustering for clustering analysis. It indicated that there were two groups in 26 species and some species with ring and membranous volva clustered a group which coincided with morphological classification.

本文对采自湖南莽山的26种鹅膏菌属真菌进行了随机扩增多态性DNA分析，40个随机引物中筛选出扩增效果较好的6个引物，每个引物能产生1～10条DNA条带，获得的RAPD谱带清晰并呈现多态性OPG15、OPH04两个引物扩增的RAPD谱带能将26种鹅膏菌完全区分开来，通过6个引物的RAPD分析获得的平均相似性系数表明种与种之间的相关系数在20―60%之间，平均链锁聚类分析可将26种鹅膏菌分为二大类，且一些具菌环和苞状菌托的种类聚在一起，与形态分类基本相吻合。

Metacyclic group, which is the expansion of a cyclic group by a cyclic group, is a special group generated by two elements.
