粒子与反粒子间的对称性深深地锲入到物理学的基础之中。
The symmetry between particles and antiparticles is woven deep into the foundations of physics.
粒子与反粒子仍然存在碰撞的机会，因为万有斥力要比电极引力弱得多。
Particles and antiparticles could still collide, however, since gravitational repulsion is much weaker than electrical attraction.
量子物理学认为，真空并不是真正是空的，而是沸腾的海洋——被称作虚粒子与反粒子的东西不停出现与消失。
According to quantum physics, empty space is not actually barren but is a boiling sea of so-called virtual particles and antiparticles constantly popping in and out of existence.
与电子的质量相等但带正电荷的亚原子粒子(是电子的反粒子)。
A subatomic particle with the same mass as the electron but positive charge (it is the antiparticle of the electron).
每一种亚原子粒子都有其反粒子。反粒子的各种性质与对应的粒子相同或相反。
Each subatomic particle has its antiparticle, its properties being equal and opposite to those of the particle.
当反粒子与相应粒子相遇，两种粒子都湮灭，相应的能量变为光子的辐射能。
When an antiparticle meets its corresponding particle, both are annihilated and the corresponding energy released as photons of radiant energy.
