对合肥和东南沿海地区气溶胶粒子的光学特性进行了较为系统地实验观测和统计分析，并初步建立了两个典型地区气溶胶光学特性的模式，对这些地区气溶胶粒子的尺度谱分布、数浓度、散射和吸收系数以及大气能见度获得了规律性认识，这有助于较为全面地了解合肥和东南沿海地区大气气溶胶粒子的各种光学特征量，并可深入了解陆地和海洋型气溶胶粒子的光学特性。

Optical properties of aerosol in the regions of Hefei and southeast coast were systematically measured and statistically analyzed. Moreover, the characteristic models were established, and the statistical laws of the parameters such as size distribution, total number concentration, scattering coefficient, absorption coefficient and visibility, were obtained. These typical results are helpful to realize other kinds of characteristic optical parameters, as well as continental and maritime aerosol.
