lepton numbers───[高能]轻子数

neutron number───n.核内中子数

Froude number───弗劳德数

we began with the proton number.───我们从质子数开始。

The proton number is in the lower left corner.───质子数是在左下方。

we get at the number of neutrons indirectly because we know the proton number here.───我们可以间接得到中子数，因为我们知道质子数了。

Using the difference between neutron and proton number in atomic nucleus, the "Element's Periodic Law of Three" .───通过原子核内中子数与质子数的差值——中质差，探讨构建“元素立体周期律”的可能性。

Using the difference between neutron and proton number in atomic nucleus, the "Element's Periodic Law of Three".

Using the difference between neutron and proton number in atomic nucleus, the "Element's Periodic Law of Threedimensional (solid)" is constructed preliminarily.
