It defragments the leaf level of clustered and nonclustered indexes on tables and views by physically reordering the leaf - level pages to match the logical , left to right , order of the leaf nodes 通过对叶级页以物理方式重新排序，使之与叶节点的从左到右的逻辑顺序相匹配，进而对表和视图中的聚集索引和非聚集索引的叶级进行碎片整理。
Standard transactional replication also supports a republishing hierarchy : updates are delivered from a publisher to a set of republishing subscribers , who in turn deliver updates to a final set of 标准事务性复制还支持重新发布层次结构：将更新从发布服务器传递到一组重新发布订阅服务器，这些订阅服务器依次将更新传递到最终的一组“叶节点”
Alternatively , an event in one component may update the visual representation of another component ; for example , clicking on a leaf node in a tree may cause an associated list to change its contents and redisplay 另外，某个组件的事件可能会更新另一个组件的显示；例如当点击一个树型控件的叶节点可能会导致和它关联的列表控件改变它的内容和显示。
Reorganizing an index defragments the leaf level of clustered and nonclustered indexes on tables and views by physically reordering the leaf - level pages to match the logical order left to right of the leaf nodes 重新组织索引是通过对叶页进行物理重新排序，使其与叶节点的逻辑顺序（从左到右）相匹配，从而对表或视图的聚集索引和非聚集索引的叶级别进行碎片整理。
