| 摘 要： | 介绍了光学测量技术在环境监测中的应用,利用多元回归方法分析了大气气溶胶数密度和质量浓度的相关性。运用该技术和方法对北京地区2月份大气气溶胶不同粒径段的粒子数密度与质量浓度进行了测量和相关性分析,得出了利用粒子数密度谱获取颗粒物(PM10)质量浓度谱的经验公式,并对公式进行了实验验证,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。

| Abstract: | The action of optical direct-reading techniques in environment monitoring was described,with analysis of relationship between atmospheric aerosol mass concentration distribution and number distribution by multiple regressions.Based on various atmospheric aerosol parameters measured in Beijing in February,empirical formulas was given for calculating atmospheric aerosol mass concentration distribution from atmospheric aerosol number distribution measured by aerodynamic particle size(APS).The study aims to provide reference to air pollutants controlling scheme and strategy for Beijing City. |
