构

A configuration is reducible if no minimal 5 chromatic plane graph can contain it.

如果没有极小5色平面图能包含某个构形，就说此构形是可约的。

Meanwhile, the isomer with a larger change of dipole moment has larger value of the first hyperpolarizability during the charge-transfer process.

5， 6， 7顶点双取代碳硼烷桥连分子受推拉电子基的影响，5， 6， 7顶点碳硼烷的构型发生一定变化，碳硼烷中两个C原子间的距离变长；同时碳硼烷中两个C原子取代位置的不同，影响了分子的稳定性和极化率，取代基团与碳硼烷中成键数较低的C原子相连的异构体，稳定性较好且具有大的极化率； 5，6，7顶点双取代碳硼烷桥连分子形成一维结构有利于分子内电荷转移，在电荷转移过程中偶极矩变化较大的体系，其二阶NLO系数也较大。

The results show that the ground state structures of CB(superscript -)(n=1~6) clusters are linear as C clusters due to their isoelectrons. For CB (n=1~6) clusters, the ground state structure of C2B is asymmetric triangle and C6B is C(subscript 2v) symmetry planar monocycle, while the other clusters are linear.

结果表明CB(n=1~6)团簇的基态构型均为线形，这与等电子的C簇合物的结构是一致的；CB(n=1~6)团簇的基态构型中，除C2B为不对称的三角形，C6B为具有C(下标 2v)对称性的环状结构外，其余均为线形结构。

However, the formation of metal chelation at one or two side of biphenyl resulted a pair of enantiomers of monometallic or bimetallic complexes. Moreover, if the coordinating groups have chiral element (e.g., chiral oxazolines), the diastereomeric metal complexes will be formed.

而且，如果配位基团上带有手性元素，它们跟金属配位后得到一对非对映异构体，由于手性元素的影响，形成这一对非对映异构体的能量是有差异的。

综述了近年来正构烷烃在分子筛为载体的双功能催化剂上加氢异构化反应机理的研究进展，介绍了单分子机理、双分子机理、孔口机理及锁匙机理，并展望了反应机理在制备新型催化剂领域的应用前景。

The _Lorwyn_ Block Constructed format will be renamed _Lorwyn-Shadowmoor_ Block Constructed and comprise the _Lorwyn_, _Morningtide_, and _Shadowmoor_ sets.

洛温_环境构组赛制将更名为_洛温-暗影荒原_环境构组赛制，包括了_洛温_，_晨光_，以及_暗影荒原_系列。

Modern Chinese ; foreign morpheme ; multisyllabic words ; morphemic syllable; word-formation pattern

现代汉语；外来构词词素；多音节化；音节词素化；构词方式

This trend helps to increase the number of multisyllabic words,enlarge affixal words and morphemic syllables,and enrich the Chinese system with diverse word-formation patterns.

它们凭借极强的能产性构成了一系列的词族，对现代汉语词汇系统产生了巨大冲击，具体表现在：现代汉语词语多音节化趋势加强；促进了现代汉语词汇词缀化或音节词素化倾向；大大丰富了现代汉语构词的方式，致使构词方式多样化。

In order to know the differences of mean vales between different groups, this study used multivariate analysis of variance. In the end, we can make a sufficient interpretation for such differences.

本研究发现，消费者对国家形象的感知大体上分为四个构面：与中国关系评价、国家发展程度、整体产品评价、整体人民评价，国家形象各构面的组成项目因不同国家而有所差异。

With the development of computer and Internet,especially the Internet used widely ,the distributing and municipalism of Enterprise Information System becomes more and more prominence.

随着计算机与网络技术的迅速发展，特别是Internet应用日益普及的情况下，现代企业信息系统的分布性、异构性和自治性的特征越来越显著，相应的企业信息资源也分布在异构的计算机环境中，信息源之间的连接表现出松散耦合的特点。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
