簇

This approach not only inherits the advantages of absolute density based algorithms which can discover arbitrary shape clusters and are insensitive to noises , but also efficiently solves the following common problems: clustering results are very sensitive to the user-deflned parameters, reasonable parameters are hard to be determined, and high density clusters are contained fully in coterminous low density clusters. With this approach, incremental clustering can also be supported effectively by defining the affected sets and seed sets of the updating objects in this approach.

聚类算法的有效性问题主要表现在三个方面：其一，聚类算法大多要求用户输入一定的参数，例如希望产生的簇的数目，而这些参数通常难以确定，特别是针对高维空间中稀疏分布的实际应用数据集，用户几乎无法给出合适的算法参数，因此非专业用户需要与数据分析专家密切配合才能保证获得理想的聚类结果，导致算法的使用极为不便；其二，聚类结果对于输入的参数值过于敏感J，往往参数值的一些轻微变化却产生聚类结果的很大差异；其三，对于高维的实际应用数据集，其数据分布往往是稀疏的、杂乱的，很难为算法选择全局的参数进行准确的聚类分析，使得聚类的质量难以保证。

Using DFT combined with the orbital localized approach and Xu's covalence new concepts on a molecular fragment, it is concluded that the covalence of copper atom is 7 in 〓-type clusters and in inorganic fullerene-like molecule 〓, and there are Cu-Cu single bonds in 〓-type clusters.

应用DFT结合轨道定域化的方法和分子片共价的新概念，提出了在〓类簇合物和无机类富勒烯分子〓〓中Cu原子的共价为7，以及化合物中Cu-Cu单键的存在；解释了通常认为这类化合物中Cu-Cu之间没有成键作用而又不能回答较短的Cu-Cu键长的问题。

It is proposed that these agglomerated products may be a precursor for hollow-onion crystal lattice growth.

根据这些团簇的排布情况，我们认为这种聚生物有可能是HO结晶晶格生长的前体

In the current file entry structure, so you know that offset +8 contains the file

这个位置获得的，所以我们现在知道这个位置应该是存放文件所占的簇的个数

This implies that ESI is used as the index into the current file

所以我们已经很清楚ESI的作用了：它是当前簇
