【摘要】 二次气溶胶作为雾霾产生的重要来源之一，为探究其形成机制及影响其生长情况的环境因子，根据不同专家学者的二次气溶胶（硫酸盐气溶胶、硝酸盐气溶胶及二次有机气溶胶 SOA）生长因素的烟雾箱模拟实验对其进行分析总结。 结果表明：大气中的各种气态物质（SO₂,NO₂,NH₃,O₃等）及环境相对湿度、酸度、细颗粒物浓度和种子气溶胶等对二次气溶胶的生长均有重大影响。 通过在此基础上更为深入研究其他鲜为人知的物质对大气污染的影响情况，以期为烟雾箱研究大气光化学污染提供理论指导和选择方法。更多还原

【Abstract】 As one of the important sources of haze, secondary aerosols （sulfate aerosols, nitrate aerosols and secondary organic aerosols SOA） were analyzed and summarized according to smoke chamber simulation experiments of different experts and scholars on their growth factors in order to explore their formation mechanism and environmental factors affecting their growth. The results show that gaseous substances （SO₂,NO₂,NH₃,O₃,etc.）, relative humidity, acidity concentration of fine particles and seed aerosols have great influence on the growth of secondary aerosols. On this basis, the influence of other little-known substances on atmospheric pollution is further studied in order to provide theoretical guidance and selection methods for the study of atmospheric photochemical pollution in smoke-box.更多还原
