Product topology and box topology are two methods for introducing topologies in general Cartesian product,both of them are generalization of the concept of finite product topology.

积拓扑与箱拓扑是在拓扑空间族的笛卡儿积上引进的2种不同的拓扑，它们都是有限积拓扑的推广，对这2种拓扑作以比较是有益的。

Based on the properties of the saturation function, it was proved that the stability region of such dynamical systems can be decomposed into Cartesian product of an invariant set of their adjoint systems and a sufficiently large ball.

结合饱和函数的特殊性质，证明了此类系统的稳定域可分解为伴随系统的不变集与一个足够大球体的笛卡尔积。

There can be several iterations within a section, you can specify an additional constraint to get a subset of the Cartesian product (constraint=), and you can repeat each one several times with different seeds.

一个代码段中会有几个迭代，你可以指定额外的限制条件来得到一个笛卡尔乘积的子集(constraint=)，你可以用不同的种子重复每一个工作几次。

In a cross join, each row from one table is combined with each row from another table, resulting in what is called a cross product or a Cartesian product.

在交叉联接中，一个表中的每一行与另一个表中的每一行合并，导致生成叉积或卡迪尔积。

The types of solution activities of Chi-chi were different in three different types of problem's situation: equal groups, Cartesian product and multiplicative comparison.

乘法问题的类型会影响琦琦解题活动的类型，也就是说，琦琦会选用不同的解题活动类型，来分别解决等组型、直积型与比较型乘法问题。

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.
