清单和区间碎片都可以用于片段索引。
Both list and interval fragmentation can be used to fragment indexes.
在单个dbspace中存储多个表或索引片段。
Storing multiple table or index fragments in a single dbspace.
UPDATESTATISTICSLOW在表和索引上生成的统计将在片段的级别上进行维护。
Statistics generated by UPDATE STATISTICS LOW on tables and indexes have always been maintained at fragment level.
在单个dbspace中可以存储同一个表或索引的多个片段，从而减少分段表所需要的dbspace总体数量。
You can store multiple fragments of the same table or index in a single dbspace, reducing the total number of dbspaces needed for a fragmented table.
它还提供三种访问数组元素的方法：标准索引、创建子数组和切片(slicing)，切片能产生维数更小的数组片段的视图。
It also provides three methods for accessing array elements: standard indexing, creating subarrays, and slicing, which produces a less dimensional view of an array segment.
与在单个dbspace中保存多个表或索引片段提高了查询性能，这样做胜过将每个分段表达式存储在不同的dbspace中。
Storing multiple table or index fragments in a single dbspace improves query performance over storing each fragmented expression in a different dbspace.
所以，给定一个名为a的序列，就可以使用数字索引(比如a[0])或片段(比如a[1：5])来访问元素。
So, given a sequence named a, you can access elements using a numerical index like a [0] or a slice like a [1:5].
此外，因为使用的是Python，所以不仅允许用户使用简单的XPath数字索引，还允许用户使用一般的片段符号。
Moreover, since this is Python, I allow users to use not only XPath simple numeric indexing but also a general slice notation.
通过远程同步(rsync)传输高效分发变化了的索引片段。
Efficient distribution of index parts that have changed via rsync transport.
使用片段语法，无需指定开始或结束索引，就可以制作现有tuple的副本。
Using the slice syntax, without specifying a starting or ending index, you can make a duplicate copy of an existing tuple.
从前面的例子中可以看到，智能统计对于所有表和索引都是通用的，不管是否是片段表或索引。
As you can see from previous example, the smarter statistics is universal to all tables and indexes regardless of whether they are fragmented or not.
由于每个索引(片段)都有自己的udi计数器，因此将根据索引(片段)的修改程度判断是否跳过或是重建索引统计。
Since each index (fragment) has its own UDI counter, the decision to skip or rebuild index statistics is done based on how much the index (fragment) has changed.
例如，刚才的代码片段在当前用户未被授权查看索引大于4的页面时，取消了转换到新页面的操作。
For example, the code snippet just shown cancels the transition to the new page if the current user is not authorized to view pages with an index greater than 4.
对于大文件(包括片段文件)，一个inode能够引用一个索引节点，而每个索引节点能够引用一个叶节点(引用多个区段)。
For large files (including those that are fragmented), an inode can reference an index node, each of which can reference a leaf node (referencing multiple extents).
