纯粹数学

Value investing treats security analysis as a purely arithmetical field of study.

价值投资对待安全分析作为一个纯粹的数学研究领域。

IGMs are a kind of experimentally new-identified optical mode, standing with apparent potential in design and application. However, the mathematical expression of IGMs under Elliptic Cylindrical coordinates, preventing us from understanding IGMs instinctively, stands a formidable challenge in application. The pure mathematical expressions of IGMs are composed by a great deal of calculation, which also bids us no help in common use. I am, therefore, prompted to build an easier mathematical approach in this study.

Ince- Gaussian modes为在实验中可见的一种崭新型态的光学模态，对於我们在应用和设计上的实现，拥有许多潜力；然而，由於IGMs是在椭圆圆柱座标系下的数学来表示，造成了我们无法直觉的去了解，也成了我们在使用上的一大考验； IGMs的不易亲近，也让我们无从进一步去了解其物理特性，若纯粹以数学出发，又包含了庞大的运算，无法达到普遍的运用，是故我希望能在这篇论文使用简单的数学描述来达成对IGMs较平易近人的理解。

The relation between the quality of subject selection and editor 's qualifications was studied. With traditional logical analysis as the first step of mathematization, the author established a mathematical model by giving up the set pattern of the pure qualitative analysis.

本文从总体上研究了选题质量与编辑人员素质之间的关系，并在其传统逻辑分析的基础上，作为数学化的第一步，试图跳出传统的纯粹定性分析的臼，而就其数学模型的建立进行了尝试与讨论。

Pure mathematics is, in its way, the poetry of logical ideas.

I teach mostly pure mathematics at liberal arts college so I might be thought a dreamy, impractical, type.

At the same time, some articles that have been studied about the theory combined pure mathematics with rough sets have been emerged, and some new mathematical notions, such as rough logic, rough ideal in semigroups, rough groups and rough subgroups, rough cosets, rough invariant subgroups and homomorphism and isomorphism of rough groups, are introduced.

同时，纯粹的数学理论与粗糙集理论结合起来进行研究已有文章出现，并不断有新的数学概念出现，如&粗糙逻辑&、&半群中的粗理想&、&粗糙陪集&、&粗糙不变子群&、&粗糙群和粗糙子群&、&粗糙群的同态与同构&。

At present , concentrate on the research of rough sets theory mainly: The popularization of the rough sets model collected, the uncertainty research of the problem, with other treatment uncertainty, fuzzy mathematics relation and complementation of theories of questions, the research of the pure mathematics theory, rough sets research and research of the artificial intelligence other directions relation that collect ,etc, some of the research is by the push that is used is produced , some of pure theories.

目前，对粗糙集理论的研究主要集中在：粗糙集的模型的推广，问题的不确定性的研究，与其他处理不确定性，模糊性问题的数学理论的关系与互补，纯粹的数学理论方面的研究，粗糙集的算法研究和人工智能其他方向关系的研究等，这些研究有的是受应用的推动而产生的，有的是纯理论的。

It is important to understand technical talk as social talk, to recognize that mathematics and mathematical objects are not (to borrow terms from the anthropologist Clifford Geertz' analysis of speech) simply "concatenations of pure form,""parades of syntactic variations," or sets of structural transformations.

（为了认识到数学和数学对象并非是简单的'纯粹形式的并列联接'、并非仅仅是句法变换、或并非是一套'结构转换'，以社会谈论理解技术谈论是重要的
