| 1 | 北京夏季高温高湿和降水过程对大气颗粒物谱分布的影响显示文摘2004—07—13~2004—08—23使用TDMPS-APS系统在线测量颗粒物的数浓度谱分布,并于07—16~07—18选取了高温闷热夜晚、日间高温高湿和雨后晴朗干洁3种天气条件,使用多级串联撞击式采样器(MOUDI)测量颗粒物的质量浓度谱分布,结果表明,高温高湿天气条件下颗粒物的污染、尤其细粒子污染严重,导致很低的能见度(2.5km);PM1.8和PM10的质量浓度分别为170.68μg/m^3和249.35μg/m^3,细粒子质量浓度占PM10的68%;粒径为50~100nm颗粒物的数浓度最高,为2×10^4~3×10^4个/cm^3;降雨过程对粗粒子和细粒子均有去除作用,对细粒子的去除作用尤为明显;降雨后PM10和PM1.8浓度分别比降雨前降低3倍和6倍;降雨过后的晴朗干洁天气有利于新粒子(3~20nm)的生成,生成的新粒子快速长大到50~100nm;随着污染物的累积,以后几天内又变为污染天气. | 胡敏 刘尚 吴志军 张静 赵云良 Birgit Wehner Alfred Wiedensohler | 2006 | 环境科学2006，27，11： | 117 |
| 2 | Evolution of particle number size distribution in an urban atmosphere during episodes of heavy pollution and new particle formation显示文摘This study discusses the evolution of particle number size distribution during episodes of heavy pollution and new particle formation in the urban atmosphere of Beijing to quantify the effects of dynamic processes (coagulation and condensation) on the particle number size distribution.During a heavy-pollution event,an extremely low number concentration of 3-10 nm particles (on average 46 cm-3) was observed.This is because nucleation-mode particles were easily removed by strong coagulational scavenging of larger particles under this condition.In addition,a large condensation sink (on average 0.13 s-1) restrained nucleation,which is one of the major sources of nucleation-mode particles.Conversely,during a new-particle formation event,the small condensation sink (0.01 s-1) of precursor facilitated nucleation.At the same time,preexisting particles had little ability to scavenge newly formed particles (around 1 nm) and allowed them to grow to a detectable size (larger than 3 nm currently).We suggest that the effects of dynamic processes (coagulation and condensation) on particle size distribution should be stressed under some extreme conditions of the relatively polluted urban atmosphere in addition to traffic and meteorological factors. | WU ZhiJun, HU Min YUE DingLi Birgit WEHNER Alfred WIEDENSOHLER | 2011 | Science China Earth Sciences2011，54，11： | 8 |
