| 1 | 北京大气颗粒物污染的区域性本质显示文摘颗粒物是北京的首要大气污染物,2006年PM10年均浓度超标60%以上.本研究基于颗粒物质量浓度在线监测和逐日TSP的采样分析,结合地面天气形势,论述了北京大气颗粒物污染的区域性特征.首先,北京大气颗粒物污染过程的形成由以冷锋过境为明显标志的周期性的天气系统决定,天气系统的活动尺度决定了颗粒物污染的区域性.其次,从PM2.5/PM10和Pb/Al比值的变化判别出颗粒物污染过程中随着颗粒物浓度的升高,细颗粒物呈现富集趋势;细颗粒物的富集由粗颗粒物的去除和超细颗粒物的生成(核化过程)、以及二次颗粒物的生成所致;污染过程中颗粒物的老化以及化学组成(Pb/Al)的大幅度变化共同表明了北京大气颗粒物来源的区域性本质. | 贺克斌 贾英韬 马永亮 雷宇 赵晴 TANAKA Shigeru OKUDA Tomoaki | 2009 | 环境科学学报2009，29，3： | 86 |

| 12 | Charging states on atmospheric aerosol particles affected by meteorological conditions显示文摘Previous studies on haze formation focused mainly on the various chemical components in aerosol particles and their physicochemical effects on particle behaviour(e.g.,generation,growth,and agglomeration).This paper describes the measurement of the charging state on atmospheric aerosol particles,which could be affected by meteorological conditions.A series of experiments on particle charging state and meteorological factors was undertaken on the roof of the west 4th building on the Qujiang Campus at Xi'an Jiaotong University(China).Measurements were conducted approximately 20 m above ground level,Our results showed that most atmospheric particles carried net negative or positive charge and that the electric charge on the particles varied diurnally and seasonally.The average amount of charge on particles was higher in winter than in summer.The number concentration of charged particles was higher during the day than overnight.Obvious difference in the average charge of aerosol particles was found between sand-dust days and haze days.A strong relationship was found between the PM2.s concentration,charge amount on particles,and humidity.Our findings show that particle formation and growth could partly be attributed to variation in particle charging state,which is related to meteorological conditions including atmospheric humidity. | Yuanping He Zhaolin Gu Weizhen Lu Liyuan Zhang Daizhou Zhang Tomoaki Okuda Chuck Wah Yu | 2020 | Particuology2020，18，5： | 0 |
