population inversion

常见例句

Being very high intensity, this focus induces a population inversion in the oxygen atoms, ensuring that there are more excited than non-excited atoms.
在高强度下，这种聚焦会使氧原子的粒子束反转，确保了激发的原子多于未被激发的原子。
Microwave emission lines with anomalous intensity ratio would be produced when the relativistic electrons move through a, molecular cloud with a certain population inversion.
相对论电子在某种粒子数反转布居的分子云中穿行时，可以产生具有反常强度比的微波发射谱线。
It is shown that the inversions of inherent pumping rate and spontaneous decay rate replace the inversion of population, and together help to realize lasing without population inversion.
我们证明初始泵浦率和能级间自发辐射率的反转代替了稳态布居数的反转，共同促进了无布居数反转光放大，而且只要前两者之一满足就可以实现无反转光放大。
