居量反轉（英語：Population inversion），又譯為群數反轉、密數反轉、集居数反轉、粒子數反轉、反轉分布，為一個物理學名詞，在統計力學中經常被使用。居量反轉即在一個系統（例如一群原子或分子）中，處在激發狀態的成員數量比起處於較低能階狀態的成員更多。讓標準雷射進入能夠運作的狀態的過程中，產生居量反轉是一個必要的步驟，因此在雷射科學中，居量反轉是很重要的研究主題之一。值得注意的是居量反轉不可能是熱平衡的穩態解，如二能階系統中，溫度極高 … Webpopulation inversion的中文翻译，population inversion是什么意思，怎么用汉语翻译population inversion，population inversion的中文意思，population inversion的中 … sharland dentist

Population inversion will happen if the no of atom in excited state N2 is higher than the no of atom in ground state i.e. N1. From the equation we can say that the ratio of N2/N1 is greater than 1 only when the thermodynamic temperature T is negative as E2 – E1 will always be positive. sharland house dental practice

"WebThus, population inversion is achieved between energy states E3 and E2. In a 4-level laser, only a few electrons are excited to achieve population inversion. Therefore, a 4-level laser produces light efficiently than a 3-level laser. In practical, more than four energy levels may be involved in the laser process. " - Population inversion中文
