Abstract: The theoretical developments and experimental study status of vapor nucleation on fine particles are reviewed. The heterogeneous nucleation theories are summarized as the classical heterogeneous nucleation theory, the density functional theory and the molecular dynamics Monte Carlo theory, and their characteristics of the three theories are analyzed. Combined with the application of water vapor heterogeneous condensation in emission control of PM2.5 from combustion, the purports and methods for the study of heterogeneous nucleation and condensation of supersaturated vapor on fine particulates are presented.

摘要： 总结了蒸汽在细微颗粒表面异质核化理论的发展与实验研究状况，将异质核化理论归纳为经典异质核化理论、密度函数理论、分子动力学Monte Carlo理论，分析了这3种理论的特点。结合蒸汽相变技术在控制燃烧源PM2.5排放上的应用，指出进行过饱和蒸汽在燃烧源PM2.5表面异质核化研究的意义与方法。
