摘要
本文利用天津气象科学研究所铁塔,在1989年冬、夏两季对天津地区气溶胶颗粒物进行了粒度分布、成份分布等的测量研究。1 气溶胶颗粒物平均地面粒度谱分布的特征 为了减少观测数据的误差和气溶胶颗粒物随机性的起伏,我们把夏季和冬季相同天气条件下的观测值加以平均。夏季采样期间天气为一致的晴朗天气,能见度大于15km。
The field experiment about atmospheric particles were conducted in Tian-jin during 1989.The results showed that the particles size distributed in partial state.Most particles ranged in the radius that were less than 2μm. Alkline materials are mainly in the coarse particles and acid materials in the fine particles. The data of the Tianjin with the data of Chongqin and Guiyang cities are compared. The results showed that the contents of sulfur element in particles were about same in Tianjin and Chongqin, Guiyang, but the alkline elements in particles were more larger in Tianjin than in Chongqin and Guiyang. It is maybe important cause that acid raia appeared in South China but scarely appered in North China.
