| 摘 要： | 利用飞机机载粒子测量系统(PMS)对河北省衡水湖自然保护区上空的大气气溶胶粒子进行观测研究。观测结果表明:下垫面、天气条件、逆温等对气溶胶的分布存在较大的影响;衡水湖上空不同高度的气溶胶平均谱分布均呈现出单峰分布;细粒子谱分布在0.28μm左右处出现峰值;多阶Γ函数对气溶胶粒子谱有较好的拟合效果。 |

| Abstract: | The optical instruments of onboard particles mearsure system were used to observe and study the aerosol particles over the Hengshui Lake in Hebei Provice.The results showed that there were several elements which had a large effect on the distribution of aerosols,such as the underlying surface,weather conditions,temperature inversion,etc.The average size distribution of aerosols in different heights above Hengshui Lake showed a single peak and it was at the particle size of around 0.28 μm.The multi-stage Γ function had better fitting results on aerosol particle spectrum. |
| Keywords: | aerosol vertical distribution horizontal distribution size distribution |
