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.
在高強度下，這種聚焦會使氧原子的粒子束反轉，確保了激發的原子多於未被激發的原子。
Microwave emission lines with anomalous intensity ratio would be produced when the relativistic electrons move through a, molecular cloud with a certain population inversion.
相對論電子在某種粒子數反轉佈居的分子雲中穿行時，可以産生具有反常強度比的微波發射譜線。
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.
我們証明初始泵浦率和能級間自發輻射率的反轉代替了穩態佈居數的反轉，共同促進了無佈居數反轉光放大，而且衹要前兩者之一滿足就可以實現無反轉光放大。
