摘要 利用自行研制的空气动力学粒谱仪和颗粒物质量监测器振荡天平,于2006年2月在北京测量了大气气溶胶的粒子数密度与质量浓度。在对二者进行相关性分析的基础上,运用多元回归方法,得出了利用粒子数密度谱获取颗粒物(PM_(10))质量浓度谱的经验公式,并对公式进行了实验验证。同时分析了北京市初春气溶胶的有关特征,以期对北京市大气污染总量控制方案及对策提供科学依据。 According to different aerosol parameters measured by aerodynamic particle sizer(APS) and tapered element oscillating microbalance(TEOM) in February 2006 in Beijing, relationship between aerosol mass concentration distribution and number distribution is described, and empirical formulas is given by multiple regression. The characteristics of atmospheric aerosol are also analyzed. It's our aim to provide references to air pollutant controlling scheme and strategy of Beijing city.
