| 1 | Size Distributions of Aerosol Sulfates and Nitrates in Beijing during the 2008 Olympic Games: Impacts of Pollution Control Measures and Regional Transport显示文摘为 2008 个奥运会,激烈的控制措施在二氧化物(SO2 ) ,氮氧化物(没有 x ) 和处理穷人的问题的另外的污染物质通风的硫的工业、城市的排出物上被实现在北京的质量。在微粒硫酸盐和硝酸盐集中以及他们的尺寸分布上调查 SO2 和没有 x 减小的效果,分离尺寸的喷雾器样品在照原尺寸的控制前后在北京在城市、顺风的农村地点用微孔的一致存款 impactors (MOUDI ) 被收集。在采样时期期间,在城市、农村的地点的好粒子(PM1.8 ) 的集体集中分别地是 94.0 和 85.9 g m3。超过 90% 硫酸盐和 60% 硝酸盐形成了同样好的粒子。得益于有益的气象学的条件和来源控制,硫酸盐在奥林匹克期间在相当低的集中并且首先在冷凝作用模式被观察。控制措施的效果独立被分析让北风和南方的 air-mass-dominated 天说明任何偏爱。在控制措施被实现以后,当在北方的空气群众占优势时,下午,硫酸盐,和硝酸盐显著地被减少,与在更大的粒子的减小的一个更高的百分比。在控制措施被实现以后,微滴模式粒子,在控制被实现以前,统治了硫酸盐和硝酸盐,显著地在集体集中被减少。但当弄脏的南方的空气群众占优势时,本地来源控制在北京测量,有效地没从北方中国平原由于庞大的地区性的贡献减少周围的硫酸盐集中。 | WANG Xinfeng WANG Tao Ravi Kant PATHAK Mattias HALLQUIST GAO Xiaomeit NIE Wei XUE Likun GAO Jian GAO Rui ZHANG Qingzhu WANG Wenxing WANG Shulan CHAI Fahe CHEN Yizhen | 2013 | Advances in Atmospheric Sciences2013，30，2： | 8 |

| 3 | Size-resolved effective density of submicron particles during summertime in the rural atmosphere of Beijing, China显示文摘Particle density is an important physical property of atmospheric particles.The information on high time-resolution size-resolved particle density is essential for understanding the atmospheric physical and chemical aging processes of aerosols particles.In the present study,a centrifugal particle mass analyzer(CPMA) combined with a differential mobility analyzer(DMA) was deployed to determine the size-resolved effective density of 50 to 350 nm particles at a rural site of Beijing during summer 2016.The measured particle effective densities decreased with increasing particle sizes and ranged from 1.43 to 1.55 g/cm^3,on average.The effective particle density distributions were dominated by a mode peaked at around 1.5 g/cm^3 for 50 to350 nm particles.Extra modes with peaks at 1.0,0.8,and 0.6 g/cm3 for 150,240,and 350 nm particles,which might be freshly emitted soot particles,were observed during intensive primary emissions episodes.The particle effective densities showed a diurnal variation pattern,with higher values during daytime.A case study showed that the effective density of Aitken mode particles during the new particle formation(NPF) event decreased considerably,indicating the significant contribution of organics to new particle growth. | Kai Qiao Zhijun Wu Xiangyu Pei Qianyun Liu Dongjie Shang Jing Zheng Zhuofei Du Wenfei Zhu Yusheng Wu Shengrong Lou Song Guo Chak K.Chan Ravi Kant Pathak Mattias Hallquist Min Hu | 2018 | Journal of Environmental Sciences2018，30，11： | 2 |
