　　七、相對論

　　Relativity theory has had a profound influence on our picture of matter by forcing us to modify our concept of a particle in an essential way. (47)In classical physics, the mass of an object had always been associated with an indestructible material substance, with some “stuff” of which all things were thought to be made. Relativity theory showed that mass has nothing to do with any substance, but is a form energy. Energy, however, is a dynamic quantity associated with activity, or with processes.(48)The fact that the mass of a particle is equivalent to a certain of energy means that the particle can no longer be seen as a static object, but has to be conceived as a dynamic pattern, a process involving the energy which manifest itself as the particle’s mass.

　　(49)This new view of particles was initiated by Dirac when he formulated a relativistic equation describing the behavior of electrons. Dirac’s theory was not only extremely successful in accounting for the fine details of atomic structure, but also revealed a fundamental symmetry between matter and anti-matter. It predicted the existence of an anti-matter with the same mass as the electron but with an opposite charge. This positively charged particle, now called the positron, was indeed discovered two years after Dirac had predicted it. The symmetry between matter and anti-matter implies that for every particle there exists an antiparticles with equal mass and opposite charge. Pairs of particles and antiparticles can be created if enough energy is available and can be made to turn into pure energy in the reverse process of destruction.(50)These processes of particle creation and destruction had been predicted from Dirac’s theory before they were actually discovered in nature, and since then they have been observed millions of times.

　　The creation of material particles from pure energy is certainly the most spectacular effect of relativity theory, and it can only be understood in terms of the view of particles outlined above.(51)Before relativistic particle physics, the constituents of matter had always been considered as being either elementary units which were indestructible and unchangeable, or as composite objects which could be broken up into their constituent parts; and the basic question was whether one could divide matter again and again, or whether one would finally arrive at some smallest indivisible units.

　　答案

　　47.在古典物理中，某一物體的質量總是與一種不可毀滅的物質相關聯。這是一種構成一切物質的“東西”。

　　48.某一粒子的質量相當于一定的能量，這一事實意味著該粒子不再被看作是一個靜態的物體，而應該被看成是一種動態的形式，一種與能量表現為粒子質量相關的過程。

　　49.這一新的粒子觀是由迪拉克首創的，他列出了描述電子運動行為的相對論方程。

　　50.粒子生成和毀滅的過程在真正被發現之前，迪拉克的理論已經對它們作出了預測，從那時起人們對此做過數百萬次的觀測。

　　51.在相對論粒子物理學誕生之前，人們一直以為物質的構成成分要么是不可毀滅和不可改變的基本單位，要么是可以分解為其構成部分的合成物。

　　總體分析

　　本文是一篇關于粒子物理理論的文章。

　　第一段：指出相對論改變了我們的粒子概念，從而影響了我們對物質的理解。

　　第二段：指出這一粒子觀點是由迪拉克首創的，他的理論揭示了物質和反物質的基本對稱。該理論已經得到了證實。

　　第三段：純能量創造物質粒子是相對論比較驚人的影響。相對論觀點的粒子物理學改變了人們對于物質的看法和理解。

　　本文是一篇科普性說明文，屬于正式文體。考生首要的任務是清楚地分析句子結構，并結合自己的物理常識準確把握生疏詞匯，在此基礎上完成翻譯。本題考核的知識點：(一)被動語態。(二)定語，包括定語從句，分詞作定語。(三)狀語從句.
