摘要
此文立足当代社会雾霾已经对人类生产生活造成严重影响的现实基础上已解析气溶胶与雾霾之间的关系为目的,在查阅大量相关资料的后分析得到雾霾与气溶胶之间的种种联系,依次点明了雾霾与气溶胶的定义,气溶胶的物理化学性质及其分类和来源,气溶胶与大气颗粒物之间的作用
关系,及气溶胶与雾霾能见度之间的关系,并得到了一定成果,气溶胶与大气颗粒物浓度息息相关,是雾霾能见度的关键因素,降低气溶胶浓度,能够显著降低雾霾发生的可能性与危害性。气溶胶可以通过雾的凝结来降低气溶胶浓度,但当城市污染严重时效率低下,将形成雾霾。当代社会人类生活生产活动大大增加了气溶胶的化学成分,不过科学家已经认识到气溶胶是雾霾的幕后黑手,并且采取了一定措施来降低气溶胶浓度。
关键词:雾霾,气溶胶,大气颗粒物,能见度,

Abstrct
This article based on the contemporary social reality thatf haze has a serious impact on the production and life of human beings. In order to analysis the relationship between aerosol and haze , after reading a lot of relevant data to analysis the connections between the haze and aerosol pointed out, that the definition of the haze aerosols, aerosol and its physical and chemical properties of the source and classification and interaction between aerosol and atmospheric particles, and the relationship between aerosol and visibility of the fog and haze, and obtained the certain achievement, aerosol and atmospheric particulate matter concentration is closely linked, which is the key factor to reduce haze visibility, aerosol concentration, it can significantly reduce the possibility and harmfulness of haze . Aerosol can be reduced by fog condensation , but when the severe pollution of the city when the efficiency is low, it will form haze. Contemporary social and human activities greatly
increased the aerosol position, but scientists have been aware of the aerosol is behind the haze, some measures have been taken to reduce the aerosol concentration .
Key word:Fog and haze, Aerosol ,Atmosphere Grain,Visibility ,
