1·Common alternatives include clustering index columns or other unique key columns.

常见的替代项包括索引列或其他唯一键列的群集。

2·Avoid having any indexes on the table, if possible, but particularly not a clustering index.

尽可能避免表上有任何索引，尤其是不要有群集索引。

3·Allowing too much free space, however, could cause extra pages to be read for queries and largely defeat the purpose of using a clustering index.

不过，如果允许太多自由空间的存在，则可能导致查询时需要读取额外的页，这反而大大违反了使用群集索引的本意。

4·This paper introduces a newly generalized and dynamic structure for the similarity retrieval of high dimensional feature vectors called the recursive clustering index tree.

文章提出了一种新的适用于高维特征矢量相似检索动态聚类索引树结构。

5·The main purpose of allocating free space is to keep the data rows in the same physical sequence as the clustering index, thus reducing the need to frequently reorganize the data.

分配空余空间的主要目的是使数据行的物理顺序与群集索引一致，以减少频繁重组数据的需要。

6·According to the experience from engineering practices and reliability theory of building structures, clustering index, quantified criterion and clustering classes are confirmed.

根据工程实践经验和结构可靠度理论，进行分析比较确定聚类指标、评定等级量化标准及聚类灰类。

7·Multidimensional Clustering (V8 GA) : Implements a form of index compression by using block indexes, one index entry for thousands of records.

多维集群(V 8 GA)：使用块索引，数千个记录共用一个索引条目，实现索引压缩。

8·The way to establish a certain data clustering property in DB2 is to reorganize the table according to an index.

在DB 2中建立数据聚集属性的方法是根据一个索引对表进行重组。

9·Under index-controlled partitioning, the concepts of partitioned table, partitioning index and clustering were all intertwined.

对于索引控制的分区方法，分区的表、分区索引和群集这几个概念之间有点纠缠不清。

10·The degree of clustering of an index; that is, the extent to which the physical sequence of rows in a table follows an index.

一个索引的群集程度；即，表中行的物理顺序与索引的符合程度。
