| 摘 要： | 为研究上海市大气中ＨＯ２自由基的分布特征，建立了化学放大法测定ＨＯ２自由基系统，对上海市大气中ＨＯ２自由基浓度进行了没定邦等结果表明，ＨＯ２自由基的典型日变化基本上为双峰型，峰值出现在阳光辐射较强的中午时分，实验测得ＨＯ２自由基最大浓度达２．２４×１０＾８分子·ｃｍ＾－３，ＨＯ２自然基民ＮＭＨＣ，Ｃ烽Ｏ２等具有一定的相关性，ＨＯ２自由基的研究对于大气光化学烟雾的研究具有重要意义

| Abstract: | Chemical amplifier was set up to determinate peroxy radical (HO2) in ambient air in Shanghai to study the distribution characteristic.Bimodal type of diurnal variation of peroxy radical was found,and the maximum HO2 concentration during a day,about 2.24×108 molecule·cm-3,occurred around noon when intensity of sunlight radiation is the greatest.The certain correlation between HO2 radical and NMHC,CO,O3 reveals the importance of research on HO2 radical for photochemical smog. |
