《示性类》内容简介:The text which follows is based mostly on lectures at PrincetonUniversity in 1957. The senior author wishes to apologize for the delayin publication.The theory of characteristic classes began in the year 1935 with almostsimultaneous work by HASSLER WHITNEY in the United States andEDUARD STIEFEL in Switzerland. StiefeI's thesis, written under thedirection of Heinz Hopf, introduced and studied certain "characteristic"homology classes determined by the tangent bundle of a smooth manifold.Whitney, then at Harvard University, treated the case of an arbitrary spherebundle. Somewhat later he invented the language of cohomology theory,hence the concept of a characteristic cohomology class, and proved thebasic product theorem.
本书收录了橡胶轮胎原材料、化学材料与助剂、生产管理、生产工艺及设备、合成橡胶生产等方面使用频率较高的词汇及专业术语等共30000余条;对英文词汇加注了音标,对中文加注了拼音。全书按照专业板块分类,各专业板块中词汇按照字母顺序排序,查阅方便。 本书对于橡胶行业内管理人员、商务人员、技术人员都有很好的参考价值。

《莫尔斯理论(英文)》主要内容简介:This book gives a present-day account of Marston Morse's theory of the calculus of variations in the large. However, there have been Im-portant developments during the past few years which are not mentioned.Let me describe three of these.

《模形式与费马大定理(英文)》中介绍和扩充讲述了wiles的许多观点和技巧,并阐述了他的结果是如何与ribets定理、frey,serre思想的结合,来证明费马最后定理。从一个完整的证明开始,紧接着用一些章节介绍了双曲线、模函数、曲线、伽罗瓦上同调和有限群的基本概念。表示理论是整个证明的核心,在一章有关自同构表示论和langlands-tunnell定理给出,紧随其后深度介绍serres猜想、伽罗瓦变形、一般变形环、hacke代数。此书以回顾和展望作为结束,既反映了这个问题的历史,又将wiles定理放在了一个更加一般的diophantine背景,给出了预期应用。数学专业的学生和老师将会发现这本书是一部很难得参考书。
《希尔伯特空间问题集(第2版)》讲述了:This book was written for the active reader. The first part consists of problems, frequently preceded by definitions and motivation, and some-times followed by corollaries and historical remarks. Most of the problems are statements to be proved, but some are questions (is it?, what is?), and some are challenges (construct, determine). The second part, a very short one, consists of hints. A hint is a word, or a paragraph, usually intended to help the reader find a solution. The hint itself is not necessarily a con-densed solution of the problem; it may just point to what I regard as the heart of the matter. Sometimes a problem contains a trap, and the hint may serve to chide the reader for rushing in too recklessly. The third part, the longest, consists of solutions: proofs, answers, or constructions, depending on the nature of the problem
《线性代数群》讲述了:For this printing, I have corrected some errors and made numerous minor changes in the interest of clarity. The most significant corrections occur in Sections 4.2, 4.3, 5.5, 30.3, 32.1, and 32.3. I have also updated the biblio-graphy to some extent. Thanks are due to a number of readers who took the trouble to point out errors, or obscurities; especially helpful were the detailed ments of Jose Antonio Vargas...
《平衡态统计物理学(第3版)》内容简介:During the last decade each of the authors has regularly taught a graduate or senior undergraduate course in statistical mechanics. During this same period, the renormalization group approach to critical phenomena, pioneered by K. G. Wilson, greatly altered our approach to condensed matter physics. Since its introduction in the context of phase transitions, the method has found application in many other areas of physics, such as many-body theory, chaos, the conductivity of disordered materials, and fractal structures. So pervasive is its influence that we feel that it now essential that graduate students be introduced at an early stage in their career to the concepts of scaling,
姜鹤编著的《双解实用机械英语》是职业教育国家规划教材,严格依据劳动部提出的“职业教育的英语教学要为专业课服务”的宗旨并结合广大职教生英语实际状况,由长期教学工作在东北老工业基地职教城一线的教师亲笔编撰而成。《双解实用机械英语》的主要内容包括:车床、铣床的结构及使用方法、工业材料的选择与加工、机械元件的类型与制造、测量技术与台面工具的使用、数控技术的编程和应用等。全书共设16个单元,每个单元包括机械对话篇、阅读理解篇、语法精讲篇和扩展训练篇等部分,其优势是考虑了职校学生英语基础薄弱的特点,为每篇课文进行了双解(解析译文,解析语法),使其成为一本无障碍读物。本教材既可作为中、高等职业学校机械类专业的英语教材:亦可成为相关行业的岗位培训手册或自学用书。
《旋量与时空(卷)》 is the first to present a prehensive development of space-time geometry using the 2-spinor formalism. There are also several other new features in our presentation. One of these is the systematic and consistent use of the abstract index approach to tensor and spinor calculus. We hope that the purist differential geometer who casually leafs through the book will not automatically be put off by the appearance of numerous indices. Except for the occasional bold-face upright ones, our indices differ from the more usual ones in being abstract markers without reference to any basis or coordinate system. Our use of abstract indices leads to a number of simplifications over conventional treatments.
