代数学

He returned to his native New Zealand to pursue research into the applications of geometric algebras in physics.

之后他回到故乡新西兰，致力于几何代数学在物理学中应用的研究。

I believe that it's very useful for Computer science students who learning Boolean algebra and predicate logic.

我相信对于学习布尔代数学和谓词逻辑的计算机科学学生来说它是非常有用的。

Secondly, what Glossematical School wants is to establish the linguistic typology, namely metatheory, helping to compare different theoretical pattern, sign systems, linguistic signs, and levels of linguistic symbol theoretical pattern, on the basis of which the study objects of glossematics are finite as relation among the previous statement, defined as function.

因为语言符号的形式和意义之间的关系是任意性的，不存在普遍意义的范畴。语言学的所有范畴都要从具体语篇中演算出来，这就要建立语言代数学，即语符学。其二是用纯理语言构建的语言模型，必须拿具体的语言去检验。模型反映出的是人类所有语篇，包括未出现的和已经消亡的语篇的各种可能性，利用语符学的经验原则和推导条件帮助识别出哪些是现实中存在的形式，哪些是潜在的形式。

George Boole develops a system of mathematics called Boolean algebra, which uses binary operations.

乔治。布尔开发采用二进位制运算的数学体系，称为布尔代数学。

In an algebra proposed by George Boole about 1850, the variables are permitted to have only two values true or false , usually written as 1 and 0, and the algebraic operations on the variables are limited to those defined as AND, OR, NOT.

George Boole 在1850年提出的代数学中，变量值只有两种：真和假，通常记为1和0，代数运算也仅局限于与、或、非。

Mr Derbyshire, whose bookhas just been published in Britain after appearing in America last year, givesan intriguing account of these developments, and of the mathematiciansinvolved, such as George Boole, who "married algebra to logic" by inventingalgebraic ways to express logical arguments: he led an almost saintly life, butdied after his wife treated him for a chill by dousing him in buckets of icywater.

德比夏尔的这本书去年在美国出版，紧接着现在又在英国上市。书中对代数学的发展和历史上的数学家做了生动有趣的描述。例如乔治·布尔，他把&代数嫁给了逻辑&，用代数的方式表达逻辑参数。乔治·布尔一生圣洁，但是却死于他妻子淋头而下的冰水所致的风寒。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
