http://www.ichacha.net/population%20inversion.html WebPopulation inversion is a state of a system, for example a laser gain medium, where a higher-lying energy level is more strongly populated than a lower-lying level. This cannot occur under conditions of thermal equilibrium, where the level populations are described by a Boltzmann distribution. However, a population inversion is often easily ...
Web5、语言顺序特殊的调整句式顺序法 词序调整法的英语inversion一词,不能译成“倒译”、“倒译法”或“颠倒词序”之类,否则容易和语法中的“倒装”概念相混淆。 inversion作为一种翻译技巧,其意思为:翻译时对词序作必要或必不可少的改变,并不只是纯粹的颠倒词序或倒装。 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.
