As the application, we obtain an upper bound of the Hausdorff measure for the Cartesian product set of the middle-third Cantor set with itself.

采用这种方法，本文得到三分Cantor集自乘积集的Hausdorff测度的一个上界。

Rationale --------- A cartesian product should be avoided whenever possible because it is an expensive operation and might produce a large amount of data.

最后导致问题的根本原因：由于迪卡尔积是一个会产生很大数据量的消耗资源的操作，所以需要尽量避免迪卡尔积操作。

In this chapter, we give out the definitionsof Cartesian product, composition, union and join for two L-graphs, which aregeneralization of the corresponding operations in graph, and the necessary conditionsthat a partial L-subgraph of these operations can be obtained by the same operationfor some partial L-subgraph of the given two L-graphs are investigated.

本章定义了两个L-图的笛卡尔积运算、合成运算、并运算和联运算(它们是图中相应运算的推广)，并研究了这些运算的部分L-子图可以由这两个L-图的部分L-子图通过相应的运算生成所需要的条件。

A database engine can make very strong assumptions about first constrain ing the heavily indexed dimension tables, and then attacking the fact table all at once with the Cartesian product of the dimension table keys satisfying the user's constraints.

数据库引擎会对具有约束并大量索引的维度表做假设，然后使用满足用户条件的维度表的主键与事实表做笛卡尔积。
