摘要
激光诱导荧光技术是目前测量大气OH 自由基中使用最多的方法。本文总结了20 多年的研究成果,论述了激光诱导荧光技术用于测定大气OH 自由基的研究进展,讨论了测量中的不确定因素及其对策,并着重介绍了目前最常用的基于气体扩张的低压荧光(FAGE) 技术。
Abstract Hydroxyl radical(OH) is the most important oxidant in the troposphere. Laser induced fluorescence (LIF) technique has been widely used in the determination of OH. In this article, the measurement of atmospheric OH using LIF technique was reviewed, especially the new FAGE technique (fluorescence assay with gas expansion). The uncertainty and its possible solutions were discussed, and future research trends were evaluated.
