| 1. | The physics of fundamental particles has been a recognized field of research only in the past 40 years .
基本粒子物理学，仅仅在最近四十年才成为被承认的一个研究领域。
|
| 2. | It is known that inside neutrons and protons there are more fundamental particles called quarks
中子和质子是由一种更基本的粒子夸克所组成。
|
| 3. | Depends on different counting methods , there are about 18 types of fundamental particles
基本粒子大约有十八种，不同的计算方法可能出现不同的数目。
|
| 4. | To understand what will happen before that , we have to study the constituents of atoms : the fundamental particles
要了解宇宙更早期的情况，我们必须研究组成原子的基本粒子。
|
| 5. | Fundamental particles have an intrinsic mass known as their rest mass ( those with zero rest mass are called massless )
基本粒子有个称为静止质量的内在质量（静止质量为零的粒子称为无质量粒子） 。
|
| 6. | One proposal is that it is some kind of weakly interacting massive particle wimp . is dark matter really some exotic fundamental particle
有科学家猜想它们是一些作用力很弱但质量非零的粒子，究竟暗物质是否一些很特别的基本粒子呢？
|
| 7. | One interpretation of why we have such a quirky list of fundamental particles is because they all result from different facets of the strange symmetries of e8
有一个解释为什么我们有如此奇特的基本粒子，这是因为它们来自于e8不同的对称的层面。
|
| 8. | The exact abundances of the three lightest elements are an important test of the so - called standard model of physics ? the list of fundamental particles found so far and the forces that link them
物理标准模式理论中有一项极为重要的试验，该试验检测的是宇宙空间中3中质量最轻元素的确切丰度，即需要列出到目前所发现的基本粒子与将它们融合起来的各种作用力。
|
| 9. | Despite several decades of trying , scientists have failed to fit einstein ' s general theory of relativity , which describes how gravity holds big objects together , with the quantum mechanics he pioneered , which describes the tiny fundamental particles of which matter consists and the forces by which they interact
尽管经历了数十年的刻苦钻研，科学家们仍然无法将爱因斯坦的广义相对论与他所开拓过的量子理论统一在一起? ?这两个理论前者是描述引力如何将大型天体维系在一起，后者则是描述组成物质的微小基础粒子以及粒子之间的相互作用力。
