1. Odd though it sounds, cosmicinflation is a scientifically plausible consequence of some respected ideas in elementary-particle physics. 宇宙膨胀说虽然听似奇特，但它是基本粒子物理学中一些公认的理论在科学上看来可信的推论。
2. A proton is an elementary particle of matter that possesses a positive charge. 质子是带正电荷的物质的基本粒子。
3. He further predicted that every elementary particle with a spin has its counterpart with the same mass but opposite electric charge, or that a particle has an antiparticle. 他进一步预言每一种自旋为的基本粒子都有质量相同但电荷相异的对应粒子，或者说，就是每个这样的粒子都有一个反粒子。
4. Particle physicists define elementary particles or fundamental particles as the smallest building blocks in the universe. 粒子物理学家将基本粒子或者称为基础粒子定义为构筑世界的最小的单元。
5. In the parlance of quantum mechanics, however, to call a particle pointlike is to say no more than that it is elementary, ie, that it is not known to be made up of smaller bits. 而在量子力学术语中，“点粒子”即为“基本粒子”（迄今还未发现有用来构成基本粒子的更小单位）。
