这意味着激发原子只能发出某种特定能量的光。

This means that the excited atoms only emit light of certain specific energies.

这种态可由压缩真空光场与激发原子间的多无子作用产生。

Such states can be produced by the multiphoton interaction between the excited atoms and the field in squeezed vacuum state.

当我们增大两个电极之间电压,我们有-我们可以把氢气2,分解成单个的氢原子，不仅这样，还能激发原子。

When we increase the potential between the 2 electrodes that we have in the tube -- we actually split the h 2 into the individual hydrogen atoms, and not only do that, but also excite the atoms.

So, electron promotion does not happen in terms of nitrogen, because it would not increased our number of unpaired electrons.

这里对于氮原子不会有电子激发，因为这不会增加,未配对电子的数目。
