- These gas lasers give off a continuous beam. 這種氣體激光器產生連續不斷光束。
- Inside the bucket, xenon gas from the propellant tank flows into an ionization chamber where an electromagnetic field tears electrons off the xenon gas atoms to create a plasma. 在這個光電桶中,氙氣由推進劑槽流入離子化室,離子化室中的電磁場使氣態氙原子的電子脫離,形成電漿。
- Presumably it became imprisoned in the cagelike structure of the aluminum phosphate minerals, which were able to hold on to the xenon gas created within them, even at high temperatures. 或許它是被磷酸鋁晶體那牢籠般的結構給囚錮住了,這種晶體即使在高溫時也能緊抓住其內部的氙。

- The main difference is that instead of relying on low-pressure mercury vapour in a longish twisted tube, the HIDs in headlamps use xenon gas under high pressure in a tough little quartz package. 主要區別在於取代了在狹長螺旋燈管中的低壓汞蒸汽,HIDs的前大燈使用石英封裝的高壓氙氣。
- The most common method to "pump" a gas laser--that is, to invert the population in the states that give rise to light amplification--is to use a gas discharge. 「發射」氣體激光(也就是反轉能產生光放大的那些狀態的粒子數)的最普通方法是運用氣體放電。
