| 摘 要： | 2001年夏季和冬季，在北京市大兴区榆垡镇，利用光学粒子计数器、能见度仪和颗粒物质量监测器对近地面大气气溶胶粒子数密度、大气能见度、颗粒物质量浓度(PM10、PM2．5和PM1．0)等进行了联合观测实验，取得了大量相关资料．本文通过对不同尺寸大气气溶胶粒子的数密度与颗粒物质量浓度及大气能见度的多元线性回归分析，给出了利用粒子数密度计算PM10、PM2．5、PM1．0和大气能见度的经验计算公式．

| Abstract: | Atmospheric aerosol number concentration, atmospheric visibility and particulate mass concentrations, such as PM10, PM2.5 and PM1.0, were detected by an optical particle counter (OPC), a visibility meter and ambient particulate monitors respectively at the same time in Beijing during the winter of 2001. According to the analysis of multivariate linear regression for particulate mass concentration and visibility with atmospheric aerosol concentration, the empiric formulas are given for calculating the visibility, PM10, PM2.5 and PM1.0 from atmospheric aerosol number distribution measured by an OPC. |

| Keywords: | atmospheric optics optical particle counter atmospheric aerosol atmospheric visibility number concentration multiple correlation coefficient |
