集合的

To take just one example, consider the set theorist's axiom of extensionality : For any sets A and B , if A and B have the same members, then A is the same set as B .

举例说，考虑集合论的外延公理：对任何集合A和B，如果A和B有相同的成员，那么A作为集合和B同一。

Let F be a bijection from set A to set B. Denote M={a Aa F}. If in a theory that ME B is legitimate, then the question m E M?

令F是从集合A到集合B的双射，记M＝aAaF，如果在某个理论中M B是合法的则问题m M？

You are no longer able to %26quot;pet-use%26quot; your units by setting their rally point

不能设置单位的集合点（或者是集合点设置无效？

Considering multiple expansion objectives (including minimizing the aggregate expansion cost and maximizing the degrees of successfulness, compatibility, and uniqueness), the purpose of this study is to design an effective expansion process to help a firm in expanding the benefit sets to fully satisfy the consumer's needs. The work presented in this paper is different from previous studies in practical situations and applications.

本研究之主要目的，即是在考量多个扩展目标（包括追求成功程度、相容程度、独特程度之极大化，及扩展成本之极小化）下，设计能力集合之有效扩展过程与方法，帮助厂商有效地扩展其优势特性集合，以满足消费者真正的需求。

Problem III Given find such thatProblem IV When Problem I or II or III is consistent, let Se denote the set of its solutions, for given , find , such thatwhere is Frobenius norm, S is Rn×p or a subset of Rn×p satisfying some constraint conditions, such as symmetric, skew-symmetric, centrosymmet-ric, centroskew symmetric, reflexive, antireflexive, bisymmetric or symmetric and antipersymmetric.

问题Ⅳ 设问题Ⅰ或Ⅱ或Ⅲ相容，且其解集合为SE，给定X0∈Rn×p，求X∈SE，使其中‖·‖为Frobenius范数，S为Rn×p或为Rn×p中满足某约束条件的矩阵集合，如对称矩阵、反对称矩阵、中心对称矩阵、中心反对称矩阵、自反矩阵、反自反矩阵、双对称矩阵、对称次反对称矩阵等。

Deletes all documents in a collection, but not the collection itself.

删除集合中的所有资料但是不删除集合本身。

One situation that I come across often is: 1 Having collections of objects, and 2 Enumerating these collections.

我经常遇到的问题是：1必须有集合对象；2枚举这些集合。

The method of object-oriented power network topology analysis based on compartment knowledge has been put out. Contingency aggregate and pre-screening method are combined to applied in automatic contingency selection. Contingency performance index has been modified in view of contingency probability. The programme such as contingency aggregate and contingency screening has been compiled.

提出基于间隔知识的面向对象结线分析方法；把预想故障集合和预筛选结合起来运用于预想故障自动选择，结合故障概率对故障行为指标进行修正，开发了预想故障集合和故障扫描等程序。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
