气溶胶是由工艺和燃烧气体、烟囱羽流和开放大气中的化学反应形成的。气溶胶的形成过程如下。（I）气溶胶前体分子在气体中反应，产生可冷凝分子。（2）可凝聚分子存款在稳定粒子和/或亚临界分子团簇上。(3)亚临界团簇生长到稳定的尺寸范围内和/或被稳定的气溶胶清除。(4)稳定的颗粒凝结，而冷凝继续发生在其表面。临界团簇直径dr对应于从开尔文关系计算的平衡粒径，
Aerosols form by chemical reactions in process and combustion gases, stack plumes, and the open atmosphere. Aerosol formation proceeds as follows. ( I ) Aerosol precursor molecules react i n the gas, producing condensable molecules. (2 ) The condensable molecules deposit on stable particles and/or on subcritical molecular clusters. (3) The subcritical clusters grow into the stable size range and/or are scavenged by the stable aerosol. (4) Stable particles coagulate, while condensation continues to take place on their surface. The critical cluster diameter, d r , corresponds to the equilibrium particle diameter calculated from the Kelvin relationship,
