N any of a group of elementary particles that have the same mass and spin as their corresponding particle but have opposite values for all other nonzero quantum numbers. When a particle collides with its antiparticle, mutual annihilation occurs 反粒子
When a particle encounters its antiparticle, they "annihilate" each other, disappearing in a high-energy flash of light.
当一个粒子遇到它的反物质的时候，他们会湮灭彼此，同时放出夺目的高能闪光。
For each particle there should be a corresponding antiparticle with exactly the same mass and lifetime but with an opposite electrical charge.
每个粒子都应该对应着一个反粒子，它们的质量和寿命完全相同，但带有相反的电荷。
Thecurrent "standard model" of physics holds that each particle -protons, electrons, neutrons and a zoo of more exotic particles - has itsmirror image antiparticle.
在当前有关物理学的“标准模型”中，包括质子、电子、中子以及大量更怪异粒子在内的每一种粒子都有其反粒子“镜像”。
