摘要
大气氢氧自由基在对流层大气化学中占有重要地位，但由于其浓度极低而活性极高，所以至今没有合适的测量方法。文章通过总结２０多年来大气氢氧自由基测量技术研究的成果，分析讨论了大气氢氧自由基浓度测量的研究现状和发展趋势。
Hydroxyl radical (OH)plays a critical role in tropospheric chemistry.But there are no reliable techniques to measure its ambient concentration due to its extremely high activity and low level in the atmosphere.This paper reviewed studies on the measurement of atmospheric OH,analyzed advantages and disadvantages of five different OH measurement techniques. Research emphases and trends of atmospheric OH measurement techniques were discussed.
