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。
A proton contains three charged quarks bound by the strong force and its radius is defined as the distance at which the charge density drops below a certain value.
一个质子由三个带电的夸克通过强相互作用力结合而形成，它的半径是由电荷密度降到某一确定值的距离来确定的。
Proton and neutron form a charge doublet .
质子和中子构成电荷双重态。
Maxwell's equations are "asymmetrical": electricity has an electron monopole and a proton monopole, each with opposite charge, but magnetism does not.
Maxwell方程组是“非对称的”：电场有一个负电极子和一个正电极子，带着不同的电荷；但磁场却没有。
Deuteron: the nucleus of a deuterium atom consisting of a proton and a neutron regarded as a subatomic particle with unit positive charge.
氘核：氘原子的原子核，由一个质子和一个中子组成，被视为带单位正电荷的亚原子。
A proton has positive charge and an electron (has) a negative charge, but a neutron has neither.
质子带有一个正电荷，电子带有一个负电荷，但这两种电荷中子都没有。
A proton has an electrical charge that is equal to that of the electron, but the proton weighs almost two thousand times as much as the electron.
