英文摘要	二次有机气溶胶(SOA)是指挥发性有机物在大气中发生光化学氧化进入到颗粒相的产物,由于其具有强烈的环境效应、气候效应和人体健康效应,因此成为大气化学研究的热点.然而由于SOA的复杂性和测量技术的限制,目前对SOA的研究还非常有限.总体来说,对SOA的研究手段主要有三种方法:实验室模拟、模式模拟和基于外场观测的SOA研究.由于SOA的研究非常广泛,本文仅综述了基于外场观测的SOA组成、来源和生成机制的研究,重点在于SOA组分的测量和总量的估算.基于外场观测的SOA研究是随着技术的发展而发展的,早期的研究仅仅能对SOA的少数物种进行测量,主要是一些有机酸和多羟基化合物;也有利用一些假设对SOA进行...; Secondary organic aerosol (SOA) is from the oxidation of atmospheric volatile organic compounds (VOCs), and accounts for a large fraction of ambient fine particles. SOA can directly and indirectly affect the solar radiation forcing, so it has great impact on global climate and regional air quality. Adverse effects of SOA on human health have also been found these years. Thus SOA study has become one of the hottest topics of atmospheric chemistry. However, due to the complexity of SOA and the limit of technology, our understanding about SOA's composition, sources and formation mechanism is very limited. The major approaches of SOA study include: laboratory simulation, modeling simulation and field measurement. This paper reviews the SOA studies basing on field measurement. The development of SOA measurement depends on the development of technology. Early studies can only measure limited polar compounds of ambient particles. Rough estimations have been made by using relatively well developed approaches, e.g. receptor model and non-biomass burning water soluble organic compounds. Tracer-yield method combines laboratory and ambient studies, and is so far the only approach that can estimate SOA from specific precursors. Development of on-line detection technique encourages new approaches to 'study SOA, e.g. EC (elemental carbon)/CO (carbon monoxide) tracer method, and AMS-PMF approach. The combination of AMS and organic tracer technique is probably the important direction of SOA study in the future.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000333500600002&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 4; minhu@pku.edu.cn; 02; 145-157; 72
