If you have two electron spins, at the same distance from one another,

相距亦为一个碳碳键长度的两电子自旋间
their energy is what?

能量有多少呢
One, two, three, four, five orders of magnitude smaller,

从图上看比上一个小了5个量级
10^5th smaller.

是上一个的10^(-5)倍
The "strong" binding that holds

氘核中
a proton and a neutron together is in the deuterium nucleus,

质子和中子间存在非常强的吸引力
that is within the nucleus,

它们同处在原子核中
not at 1.54 Angstroms,

其间的距离远没1.54埃
is 10^5th stronger than Coulombic interaction.

比库伦引力要强上10^5倍
And gravity is ever so much weaker.

重力就更弱了
If you had two carbon atoms, that were at that distance,

距离这样近的两个碳原子之间的万有引力
the energy would be 10^(-32) kilocalories/mol.

大概只有10^(-32)千卡/摩尔
