population inversion

常見例句

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(qiáng)度下，這種聚焦會使氧原子的粒子束反轉(zhuǎn)，確保了激發(fā)的原子多于未被激發(fā)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(shù)反轉(zhuǎn)布居的分子云中穿行時，可以產(chǎn)生具有反常強(qiáng)度比的微波發(fā)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.
我們證明初始泵浦率和能級間自發(fā)輻射率的反轉(zhuǎn)代替了穩(wěn)態(tài)布居數(shù)的反轉(zhuǎn)，共同促進(jìn)了無布居數(shù)反轉(zhuǎn)光放大，而且只要前兩者之一滿足就可以實現(xiàn)無反轉(zhuǎn)光放大。
