它能让粒子通过不可逾越的物理障碍，或让电子不用动能就脱离原子核的吸引力。
It can allow a particle to pass through a physical barrier that should be impenetrable, or can allow an electron to escape from the pull of the nucleus without having the kinetic energy to do so.
人们将“电磁吸引力”“描绘成”是由于“称作”“光子”的“无质量的”自旋为1的“粒子”的交换所引起的。
The electromagnetic attraction is pictured as being caused by the exchange of large Numbers of virtual massless particles of spin 1, called photons.
地球使每一粒子或物体保留于地球表面的吸引力称为地心引力。
The attraction that the earth has for every particle or body on its surface is called gravitation.

The attraction that the earth has to every particle or body on its surface is called gravitation.
如果亚原子粒子间的吸引力再弱一点，氢原子就会悬浮不定，也就没有了原子分子，生命也不存在了。
If the forces that bind together subatomic particles were just a little weaker, there would be a lot of hydrogen floating around, but no atoms, no molecules, and again, no life.
