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。

《柯林斯英汉双解大词典》

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。

If you look at the ground state in two different systems -If you look at the ground state which is n equals one, think about this, if I increase the proton charge, the Coulombic force of attraction is greater.

如果你观察两个不同系统的基态,当你观察n，等于1的基态时，试想一下，如果我增加质子电荷，相互吸引的库仑力就会更大。
