簇

The coalescence of helium clusters has been investigated in great detail in a range from room temperature to 800 K.

在从室温到800K的温度范围内模拟了钛基底中氦团簇之间的融合过程。

He read without a variation in expression, without his skin changing color, without an alteration in his breathing, his cockatoo's tuft of hair unmoved by the rhythm of his thoughts.

他读的时候气定神闲，面不改色，头上那簇"鹦鹉发冠"也不见随着思绪的节奏起伏。

A codebook consisting of the clustered vectors is stored, representing the characteristics of the image.

由存储的一簇矢量组成的一个码本表示图像的特征。

Branches usually several to many, clustered at mid-culm and basal nodes, central 3 codominant; branchlets usually specialized into weak or tough thorns.

通常的分枝数枚到多数，在中间秆和基部的节，中心的3 codominant的簇生；小枝通常专业化进弱或者坚韧的棘刺。

If cohomology with integer coefficients is used, so that

它在霍奇的著述的一个结果中出现，他在1930至1940年间通过包含额外的结构丰富了德拉姆上同调的表述，这种结构出现于代数簇的情况。

The most important idea is that over the complex numbers, an elliptic curve looks like a torus, and the points of finite order in the group of the curve have a very simple geometric description.

最重要的思想是复数域上的椭圆曲线是一个环面，曲线簇中的有限阶点有简单的几何描述。

The optimization methods of database SQL query were studied and some available query optimization Methods were given out as follows: The incompatible data type should avoid to be used; More redundancy search parameters should be given as join condition in join query; In some condition, the number of note hitted to target was estimated by optimizing implement using the average density; Some other maths operating symbol should avoid to be used as condition parameters in WHERE clause; Some operating symbol and its sentence should avoid to be used also; When the cluster function was used,the WHERE clause should be paied attention to more,and so on.

作者单位：（重庆工学院商贸信息学院，重庆 400050）摘要：数据库SQL查询语句的优化，须注意：避免使用不兼容数据类型；连接查询中应多给连接条件提供一些冗余的搜索参数；某种条件下优化器只能使用其平均密度以估计命中的记录数；避免对WHERE子句中条件参数使用其它数学操作符；避免使用某些操作符及相应语句；聚簇函数的使用应注意WHERE子句。

In chapter 4,taking the CCSD results as references,the performances of five DFT(BHandHLYP,MPWB1K,B3LYP,B3PW91 and SVWN) and two WFT(HF and MP2) methods for describing relative conformer energies,vertical electron detachment energies,deprotonation energies,and proton affinities of 22 amino acids were determined.

第4章中以高精度的耦合簇方法的计算结果为基准，测试了五种密度泛函方法(BHandHLYP，MPWB1K，B3LYP，B3PW91和SVWN)和两种波函方法(HF和MP2)对描述22种氨基酸体系的构型相对能量，垂直电离能，质子化和去质子化能这四种能量性质的能力。

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。
