內容簡介

This book is a modern pedagogic introduction to the ideas and techniques of quantum field theory.
After a brief overview of particle physics and a survey of relativistic wave equations and Lagrangian methods，the quantum theory of scalar and spinor fields， and then of gauge fields，is developed The emphasis throughout is on functional methods，which have played a large part in modern field theory. The book concludes with a brief survey of `topological' objects in field theory and，new to this edition，a chapter devoted to supersymmetry.

學必須依靠語言作為唯一的傳達信息的方法，並且在傳達中，在無歧義性問題具有最大的重要性的地方，邏輯形式必須起它們的作用。在這點上，特徵性的睏難可以描述如下。在自然科學中，我們試圖從一般導齣特殊，試圖理解由簡單的普遍規律引起的特殊現象。用語言錶述的普遍規律隻能包含少量簡單的概念——否則規律將不是簡單和普遍的瞭。從這些概念要推導齣無限多樣性的可能現象，不僅是定性地，而且要在每一個細節上都以完全的準確性推導齣來。顯然，日常語言的概念，既然它們是不準確的並且是模糊地定義的，就決不能允許作這樣的推導。當從既定的前提導齣判斷的鏈條時，鏈條中可能有的環的數目依賴於前提的準確性。由此可見，自然科學中普遍規律的概念必須以完全的準確性規定下來，而這隻有用數學的抽象方法纔能做到。
