摘要
过氧自由基是大气中重要的氧化剂 ,其浓度的测定对于深入理解大气化学过程具有重要意义。本文总结了二十多年的研究成果 ,论述了大气过氧自由基测量的研究进展 ,介绍了带基体分离的电子自旋共振技术、远红外及毫米波发射光谱技术、激光诱导荧光技术以及化学放大法等常用测量方法及测量结果 ,并展望其未来的发展。
Peroxy radicals are important oxidants in the troposphere.Their measurement is of special importance in the deep understanding of atmospheric chemical processes and the test of chemical model.In this paper,the measurement methods of peroxy radicals in the atmosphere were reviewed,which include matrix isolation electron spin resonance,far infrared red and millimeter wave emission spectroscopy,laser induced fluorescence and chemical amplification.Some results were presented,and future research trends were evaluated.
