　　5、The Dirac equation and the Dirac field
　　The Standard Model is a quantum field theory．In Chapter 4 we discussed the classical electromagnetic field．The transition to a quantum field will be made in Chapter 8．In this chapter we begin our discussion of the Dirac equation，which was invented bv Dirac as an equation for the relativistic quantum wave function of a single electron．However,we shall regard the Dirac wave function as a field．Which will subsequently be quantised along with the electromagnetic field．The Dirace quationwillberegardedasafieldequation．Thetransitiontoaquantumfieldtheory
　　iS called second quantisation．The field。like the Dirac wave function．is complex．W_e shall show how the Dirac field transforms under a Lorentz transformation．And find a Lorentz invariant Lagrangian from which it may be derived．
　　On quantisation，the electromagnetic fields A(x)，Fv(x)become space-and time．dependent 0perators．The expectation Values of these operators in the environ- ment described by the quantum states are the classical fields．The Dirac fields(x) alSO become space-and time．dependent operators on quantisation．However,there are no corresponding measurable classical fields．This di骶rence reflects the Pauli exclusion principle，which applies to fermions but not to bosons．In this chapter and in the following two chapters，the properties of the Dirac fields as operators are rarely invoked：for the most part the manipulations proceed as if the Dirac fields were ordinary complex functions，and the fields Can be thought of as single-particle Dirac wave functions．
　　5．1 The Dirac equation
　　Dirac invented his equation in seeking to make Schr6dingerS equation for an elec-tron compatible with special relativity．

前言/序言

　　In the eight years since the first edition， the Standard Model has not been seriously discredited as a description of particle physics in the energy region ([2 TeV) so far explored. The principal discovery in particle physics since the first edition is that neutrinos carry mass. In this new edition we have added chapters that extend the formalism of the Standard Model to include neutrino fields with mass， and we consider also the possibility that neutrinos are Majorana particles rather than Dirac particles.
　　The Large Hadron Collider (LHC) is now under construction at CERN. It is expected that， at the energies that will become available for experiments at the LHC (~20 TeV)， the physics of the Higgs field will be elucidated， and we shall begin to see　physics beyond the Standard Model. Data from the B factories will continue to accumulate and give greater understanding of CP violation. We are confident that interest in the Standard Model will be maintained for some time into the future.
　　Cambridge University Press have again been most helpful. We thank Miss V. K.Johnson for secretarial assistance. We are grateful to Professor Dr J. G. K6rner for his corrections to the first edition， and to Professor C. Davies for her helpful correspondence.

今天刚刚拿到书，这本:..王洪君1.王洪君等写的博雅21世纪汉语言专业规划教材语言学纲要（修订版）学习指导书很不错，商品博雅21世纪汉语言专业规划教材语言学纲要（修订版）学习指导书有两种印刷封面，随机发货！:10.360.100018000-1484670.博雅21世纪汉语言专业规划教材语言学纲要（修订版）学习指导书是适合使用该教材的老师和学生使用，也可供高校其他语言类课程的老师、学生及语言学爱好者参考。全书主要由教学指导和习题两大部分组成，以教材各章为序分章，习题分章后附。本书文字版不附习题答案，这是因为，这些习题有的需要学生自己从教材或指导书中去寻找答案，有的需要学生运用所学知识做出自己的分析，还有的是开放性的，没有唯一的答案。不附答案有利于促进学生思。此外，各章所需延伸阅读的文献及出处可利用教材的脚注，本书不再另外给出。三种符号中视觉符号和听觉符号应用比较多。形式和意义作为符号的构成要素是不可分的。这里要区分形式和物质材料两个不同的概念。符号中与意义相联的是形式，不是具体的物质材料。同一符号形式可以体现为具有某种共性特征的不同的具体物质材料。物质材料是可以独立存在的，只有作为符号形式的体现时，才有意义，否则没有意义。反过来说，没有意义，物质材料照样存在，但没有意义就根本谈不上符号的形式。比如，路上汽车的喇叭声是一种听觉符号，它的意义是提醒路上的行人和其他车辆注意有汽车过来。喇叭声是一种物质音响，是通过汽车内的装置发出的。走在路上，听到汽车喇叭声，便知道在提示有车过来了，这个喇叭声是符号形式的体现。不管是在哪条大街上，是哪一辆行驶的汽车发出的喇叭声，都具有同样的意义，因为它们是同一个符号形式的不同物质体现。但如果购买车辆时为了测试性能按按喇叭，发出同样的音响，却没有提示有车辆过来的意思，这时的喇叭声不是符号形式的体现，而只是单纯的物质音响。区分了符号的形式和作为形式体现的物质材料两个层次，就容易理解符号的一般性了。符号的形式和意义都是一般性的，但符号的使用是具体的。每一次符号的运用都是依托某一具体的物质材料，同时符号的意义也是和具体的情境结合在一起的，具有特殊性。符号的形式和意义之间没有本质上的、自然属性上的必然联系。这是符号的一个重要的基本性质。在这一点上，符号和隐含某种信息的自然的征候不同。征候是事物本身的特征，它传递的某种信息，可以通过它自身的物质属性来推断。例如，路上的行人听到身后有汽车行驶的声音，同样可以知道有汽车过来了。但汽车行驶的声音不同于汽车喇叭声，它不是符号。汽车行驶时由于发动机转动以及车轮在路面的摩擦等自然会发出音响，是汽车行驶本身具有的
