| 摘 要： | 2007年8月,利用粒谱分析仪(APS)、振荡天平颗粒物分析仪(TEOM)和碳黑分析仪(BC)观测北京市大气气溶胶可吸入颗粒物(PM10),研究高湿度气象条件对气溶胶颗粒物吸湿长大的影响.结果表明,PM10质量浓度与碳黑质量浓度在静稳天气状况下相关系数达0.82,而对于颗粒物数浓度与PM10质量浓度,静稳与非静稳天气状况下两者的相关性并不一致,颗粒物数浓度及1μm的细粒子在粒谱分布中所占的比重显著增加.气溶胶颗粒物粒谱变化结果说明,在高湿度条件下颗粒物粒径明显吸湿增长.

| Abstract: | In order to research the effect of high humidity on the growth of aerosol particles,the APS,TEOM and BC instruments were used to monitor the aerosol in Beijing during August,2007.The results show that,under steady-state weather condition,the correlation coefficient between the mass concentration of PM_10 and BC aerosol is 0.82,but the correlation between the number concentration and the mass concentration of PM_10 is not in accordance with that under non-steady-state weather condition.Tie number concentrati... |
