When an atom shoots out a photon of light, it recoils like a gun. 原子發(fā)出光子時(shí)，會(huì )象槍一樣地反沖。
The mass-loss includes the light radiation and solar wind. 太陽(yáng)質(zhì)量損失包括光子輻射和太陽(yáng)風(fēng)造成的質(zhì)量損失。
But most of the drugs has tew fluorescence quantum yield, so some reagents must be added to produce fluorescence. 間接測定法是由于大部分藥物本身無(wú)熒光或者在水溶液中的熒光量子產(chǎn)率低，無(wú)法直接測定藥物熒光，必須通過(guò)加入其它試劑提高藥物的熒光量子產(chǎn)率而建立的熒光分析法。
Ordinarily, random thermal jigging of the molecules prevents sound waves from behaving analogously to light quanta. 通常，分子的隨機熱運動(dòng)，會(huì )讓聲波的行為和光量子有別。
