Secondary organic aerosol (SOA) is a very important component of fine particulate matter (PM) in the atmosphere. However, the simulations of SOA, which could help to elucidate the detailed mechanism of SOA formation and quantify the roles of various precursors, remains unsatisfactory, as SOA levels are frequently underestimated. It has been found that the performance of SOA formation models can be significantly improved by incorporating the emission and evolution of semivolatile and intermediate-volatility organic compounds (S/IVOCs). In order to explore the roles of S/IVOCs in SOA formation, this study reviews some simulation models which could consider S/IVOCs for SOA formation as well as the development of emission inventories of S/IVOCs and S/IVOC modules for SOA formation. In addition, the future research directions for simulations of the effect of S/IVOCs on SOA formation are suggested.
二次有机气溶胶（SOA）是大气中细颗粒物（PM）的一个非常重要的组成部分。然而，对SOA的模拟仍不尽人意，尽管其有助于阐明SOA形成的详细机制并量化各种前体的作用，但SOA水平经常被低估。研究发现，通过纳入半挥发性和中挥发性有机化合物（S/IVOCs）的排放和演化，SOA形成模型的性能可得到显著改善。为了探究S/IVOCs在SOA形成中的作用，本研究回顾了一些可考虑S/IVOCs用于SOA形成的模拟模型，以及S/IVOCs排放清单和用于SOA形成的S/IVOC模块的发展情况。此外，还提出了未来关于S/IVOCs对SOA形成影响的模拟研究方向。
