The formation situation of the band for transition metallic carbonyl cluster compounds is analysed with the bond valence formula for atomic cluster compounds.

本文运用原子簇化合物键价计算公式，对过渡金属羰基簇合物成键情况进行了分析，利用金属键轨道数，价非键轨道数和金属配体成键轨道数计算簇合物价轨道总数。

As the Brownian movement of water quickened, the solvency must enhanced as consequence, therefore, the chance of the small water molecular clusters entering the cell wall would be increased and affect the biomacromolecule.

如果我们将微观水分子簇宏观化，可以得出小水分子簇甚至单个水分子簇与周围的物质接触面积增大，那么水分子与周围物质之间的相互作用必然加快。

As well as activity was exhibited. Theaddition of cinchonidine led to a remarkable increase in the reaction rate, as confirmed bythe IR study that the modifier activates the carbonyl groups of the reactant through itsquinuclidine nitrogen. On the contrary,〓 exerted a strong inhibition effect on theenantioselective hydrogenation. Chapter 3 Finely dispersed polyvinylpyrrolidone-stabilized iridium andbimetallic clusters were prepared by the alcohol-water reduction method.

第三章 采用醇水还原的方法制备了聚乙烯基吡咯烷酮稳定的铱纳米簇及双金属纳米簇，对丙酮酸甲酯的催化氢化表明，在铱金属簇催化体系中，辛可尼定不仅诱导了一定的对映选择性，同时对反应活性有明显的促进作用，平均反应速率可提高2-6倍。

The storage parameters set for the cluster always control the storage of all tables in the cluster.

一个簇内的所有簇表都使用此簇的存储参数来控制其空间分配。

We have produced the Argon cluster with the room temperature, and the deuterium cluster with low temperature respectively.

本文建立常温、低温气体团簇的制备系统，并制备出大尺寸的氩团簇和氘团簇。

Dos and windows in the system, the allocation of disk files for the cluster, a cluster is only assigned to a document, regardless of the document, using the entire capacity of the number of clusters.

因为在 dos 和 windows 系统中，磁盘文件的分配是以簇为单位的，一个簇只分配给一个文件使用，不管这个文件占用整个簇容量的多少。

Cluster of disk space is allocated for the unit, as the disk is a disk cluster distribution, release, read out the smallest spatial unit, even if only one byte of the documents have to occupy a whole cluster of disk storage space.

磁盘空间是以簇为单位进行分配的，由于磁盘簇是磁盘进行分配、释放、读出的最小空间单位，即使只有一个字节的文件也要占用整整一个簇的磁盘存储空间。

Clustering divides a set of physical or abstract object into several clusters that constitutes for the similar object, the object in the same of cluster are similar each other, but the object in the different cluster are dissimilitude each other.

聚类分析就是将一组物理或抽象对象，分组为类似对象组成的多个簇，在同一个簇中的对象彼此相似，不同簇中的对象彼此相异。

A sub variety of idempotent semiring variety which satisfies the additional identity and is given in this paper.

给出了满足附加等式x+xy+x≈x+y，x+xy≈xy的幂等元半环簇 I的一个子簇，讨论了该簇中成员的一些性质，并得到了这些性质的几个等价刻画和其成员的Mal'cev积分解。

The purpose of this thesis is to obtain physical information on carbon cluster growth at atomic levels, including the isomer spectrum and the mechanism of the cluster formation.

本文的主要目标在于从原子水平上获取碳团簇形成过程中的物理信息，包括团簇异构体谱以及团簇形成的动力学机制。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
