二元运算

This method will spilt the polygon and we can use this property to proceed Boolean operation of geometric polygon.

本论文中所使用的计算几何理论为二元空间分割法，此方法会对本身多边形进行分割，我们可以利用这个特性去进行几何图形的布林运算。

It introduces the basic knowledge and ideas of mathematical logic and classic set theory, including proposition logic and predicate logic, reasoning calculus and theorem proving methods, basic operations and properties of sets and relations, functions of any sets and their properties, the cardinals of infinite sets, and the applications of knowledge and ideas above in computer sciences.

本课程系统介绍数理逻辑与朴素集合论的基础知识，包括：命题逻辑和谓词逻辑、定理的推理演算和机器证明方法，集合和二元关系的基本运算和性质、任意集合中的函数及其性质，无穷集合的基数，以及上述知识在计算机科学中的应用。

In the method,based on the traditional ideas of maximal tree clustering method,the dyadic semantic representation is used to process the linguistic assessment information,and the clustering objects are classified.

该方法依据传统的最大树聚类分析方法的基本思想，采用二元语义概念对语言评价信息进行处理和运算，并对聚类对象进行分类，具有概念清晰、计算简单、信息处理较为精确的特点。

By the definition of Vague values——the elements in the closed subinterval set of the unit interval [0,1],some new definitions of binary Vague relations,operations of relations,inverse relations,compositional operations and λ-cut relations are introduced.

通过对单位区间[0，1]的闭子区间集中的元素——Vague值的定义，引入二元Vague关系、关系运算、逆关系、关系的合成、λ-截关系等新的定义。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
