| 摘 要： | 利用SJAC-MOBIC在2000-05～2000-09的3个采样时段测量了北京大气中的气溶胶SO42-、NO3-、NO2-、Cl-及相关气体组分,得出了这些污染组分的逐时变化.结果表明气溶胶Cl-、NO2-、NO3-及气体HCl、HNO2和HNO3有明显的变化规律,SO2和气溶胶SO42-的变化取决于SO2的排放,SO42-的峰值一般比SO2的峰值晚2h左右.

| Abstract: | The measurement was made in 3 periods from May to September of 2000 in Beijing. The measurement species included SO42-, NO3-, NO2-, Cl- of aerosol and related gases. The hourly variation of the concentration was presented. It showed that NO3-, NO2-, Cl- of aerosol and HCl, HNO2, HNO3 of gas varied with regularity . The variation of gas SO2 and aerosol SO42- depended on the emission of SO2. The peak time of SO42- was about 2 hours later than SO2. |
