中文摘要：

喷雾器的大小光特征在北京并且在 Xinglong 天文台与光电的喷雾器比浊计(PhAN ) 被执行，它被定位北京的 150 km 东北。喷雾器尺寸分布借助于反的问题答案被检索。好喷雾器部分的吝啬的体积尺寸分布与在范围的最大的半径是单峰的 0.110.15 m。在北京的空气盆的喷雾器物质的累积主要由于粒子尺寸，然而并非他们的数字的生长发生。检测喷雾器 nonsphericity 的一个简单光方法被建议。

英文摘要：

Measurements of aerosol optical characteris- tics were carried out with a Photoelectric Aerosol Nephelometer （PhAN） in Beijing and at Xinglong Obser- vatory, which is located 150 km northeast of Beijing. Aerosol size distributions were retrieved by means of the inverse problem solution. Mean volume size distributions of the fine aerosol fraction were unimodal with the maximum radius in the range 0.11-0.15 pm. Accumula- tion of aerosol matter in the air basin of Beijing takes place mainly due to the growth of particle size, but not their number. A simple optical method to detect aerosol nonsphericity is proposed.
