激光光谱技术在环境监测中的应用专题系列(Ⅳ)激光光谱学方法测量大气中OH自由基

THE MEASUREMENT OF HYDROXYL RADICALS BY LASER SPECTROSCOPY

OH自由基是大气中起核心作用的一种微量成分 ,其定量测量一直是环境化学研究的一个难点 .激光光谱学方法由于其诸多优点而在这一领域有着较为成功的应用 ,文章综述了其中最重要的三种 :激光诱导荧光法。

Hydroxyl radicals play a key function in the atmosphere. The measurement of OH radicals is very important in the study of atmosphere chemicals, and laser spectroscopy has been successfully applied to this field. Three important methods of laser spectroscopy, laser induced fluorescence, long\|path absorption and ring\|down spectroscopy are reviewed.
