　　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.

今天剛剛拿到書，這本:..王洪君1.王洪君等寫的博雅21世紀漢語言專業規劃教材語言學綱要（修訂版）學習指導書很不錯，商品博雅21世紀漢語言專業規劃教材語言學綱要（修訂版）學習指導書有兩種印刷封麵，隨機發貨！:10.360.100018000-1484670.博雅21世紀漢語言專業規劃教材語言學綱要（修訂版）學習指導書是適閤使用該教材的老師和學生使用，也可供高校其他語言類課程的老師、學生及語言學愛好者參考。全書主要由教學指導和習題兩大部分組成，以教材各章為序分章，習題分章後附。本書文字版不附習題答案，這是因為，這些習題有的需要學生自己從教材或指導書中去尋找答案，有的需要學生運用所學知識做齣自己的分析，還有的是開放性的，沒有唯一的答案。不附答案有利於促進學生思。此外，各章所需延伸閱讀的文獻及齣處可利用教材的腳注，本書不再另外給齣。三種符號中視覺符號和聽覺符號應用比較多。形式和意義作為符號的構成要素是不可分的。這裏要區分形式和物質材料兩個不同的概念。符號中與意義相聯的是形式，不是具體的物質材料。同一符號形式可以體現為具有某種共性特徵的不同的具體物質材料。物質材料是可以獨立存在的，隻有作為符號形式的體現時，纔有意義，否則沒有意義。反過來說，沒有意義，物質材料照樣存在，但沒有意義就根本談不上符號的形式。比如，路上汽車的喇叭聲是一種聽覺符號，它的意義是提醒路上的行人和其他車輛注意有汽車過來。喇叭聲是一種物質音響，是通過汽車內的裝置發齣的。走在路上，聽到汽車喇叭聲，便知道在提示有車過來瞭，這個喇叭聲是符號形式的體現。不管是在哪條大街上，是哪一輛行駛的汽車發齣的喇叭聲，都具有同樣的意義，因為它們是同一個符號形式的不同物質體現。但如果購買車輛時為瞭測試性能按按喇叭，發齣同樣的音響，卻沒有提示有車輛過來的意思，這時的喇叭聲不是符號形式的體現，而隻是單純的物質音響。區分瞭符號的形式和作為形式體現的物質材料兩個層次，就容易理解符號的一般性瞭。符號的形式和意義都是一般性的，但符號的使用是具體的。每一次符號的運用都是依托某一具體的物質材料，同時符號的意義也是和具體的情境結閤在一起的，具有特殊性。符號的形式和意義之間沒有本質上的、自然屬性上的必然聯係。這是符號的一個重要的基本性質。在這一點上，符號和隱含某種信息的自然的徵候不同。徵候是事物本身的特徵，它傳遞的某種信息，可以通過它自身的物質屬性來推斷。例如，路上的行人聽到身後有汽車行駛的聲音，同樣可以知道有汽車過來瞭。但汽車行駛的聲音不同於汽車喇叭聲，它不是符號。汽車行駛時由於發動機轉動以及車輪在路麵的摩擦等自然會發齣音響，是汽車行駛本身具有的
