北京地区气溶胶粒度谱分布初步研究

Preliminary Research on the Size Distribution of Aerosols in Beijing

对北京地区气溶胶数浓度及其谱分布特征进行了初步研究 ,重点探讨了气溶胶数浓度分布与相对湿度的关系。研究结果表明 ,气溶胶浓度和谱分布存在明显的日变化和逐日变化 ,并在很大程度上受空气相对湿度和里查森数影响。

Particle counter is used to study the size distribution of aerosols in Beijing The relationship between aerosol size distribution and air density is discussed The research results show that the size distribution, diel change, daily variation have a good connection with relative humidity and Richardson number
