| 摘 要： | 针对时态查询与时间属性紧密相关的特点，利用时间区间作为改进后B+-tree的索引关键字建立索引，改进后的B+-tree命名为Changing B+-tree(CB+-tree)。实验证明，在CB+-tree上进行时态查询比B+-tree及基于DOM的XML文档的查询效率有所提高。

| Abstract: | Focused on the close relative between temporal queries and time attribute, this paper uses temporal interval as an index key of the modified B+-tree to create indexes. The modified B+-tree is denoted Changing B+-tree(CB+-tree). Through the experiments, new index method processes several typical queries in temporal XML better than querying in B+-tree index and DOM method. |
