Analysis of aerosol number concentration and mass concentration using APS
利用APS分析大气气溶胶数浓度和质量浓度

Aerosol number and mass concentrations in rural area at Hefei city were measured simultaneously with home-made aerodynamic particle sizer(APS) and tapered element oscillating microbalance(TEOM).An empirical formulas was developed using multiple regression based on the relationship of number and mass concentration.Mass concentration of PM_(2.5) was calculated and its percentage in PM_(10) was also illustrated.Diurnal variations of number and mass concentrations of PM_(10) were presented and its cause has been discussed,which will provide scientific base for air pollution control strategy and methodology in Hefei city.
