乘积

A join is a Cartesian product of two row sets, with the join predicate applied as a filter to the result.

一个连接是两个行集的笛卡尔乘积，谓词连接作为一个过滤结果应用。

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。

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。

The causes of shield tunnel defections could be divided into six branches: the segment dislocations, lining material deterioration and seepage. etc. Fault trees are also founded to illustrate each branch. 23 quantitative elements from the fault trees are selected to serve as the diagnosis indexes, all of which could be applied in engineering practice. By using the AHP method, a 3-level diagnosis index system is established. Afterwards, the procedure of setting up the quantitative judging criteria is given, as well as the relative index weight of index layer, by using the improved Analytic Hierarchy Process-multiplication scale method. At last, the values of corresponding parameters of membership functions are set, with the Cauchy distribution model.

将盾构隧道常见病害成因分为管片错位、衬砌材质劣化以及渗漏水等6个子系，对每个子系构建了病害故障树；从工程应用角度出发，从故障树中选取了23个可定量化因素作为评价指标，通过层次分析法建立了三层病害评价指标体系；对体系中单一评价指标的定量化分级方法进行简述，并给出所有指标的建议分级标准，采用改进的层次分析法－乘积标度法确定了各评判指标之间的相对权重；确定了基于Cauchy分布模型的隶属函数的关键参数。

A fast algorithm for calculating the inverse and Moore-Penrose inverse of the permutation factor circulant matrix is presented. Then, a fast algorithm for the product of the permutation factor circulant matrix is given. Finally, The least-square solutions of inverse problems and the optimal approximation problems for the permutation factor circulant matrix are discussed.
