As a representative species of intermediate volatile organic compounds (IVOCs), long-chain alkanes are considered to be important precursors of secondary organic aerosols (SOA) in the atmosphere. This work reviews the previous studies on long-chain alkanes in the atmosphere: (1) the detection methods and filed observations of long-chain alkanes in both gas and particle phases are summarized briefly; (2) the laboratory studies of long chain alkanes are reviewed, the kinetic data, reaction mechanism, SOA yields, and physicochemical properties of SOA are included in detail; (3) the research progress related to model simulations of long-chain alkanes are also discussed. In addition, based on available research results, several perspective contents are proposed that can be used as a guideline for future research plans.
作为中等挥发性有机化合物（IVOCs）的代表性物种，长链烷烃被认为是大气中二次有机气溶胶（SOA）的重要前体物。本文综述了以往关于大气中长链烷烃的研究：（1）简要总结了气相和颗粒相中长链烷烃的检测方法和实地观测结果；（2）综述了长链烷烃的实验室研究，详细介绍了动力学数据、反应机理、SOA产率以及SOA的物理化学性质；（3）还讨论了与长链烷烃模型模拟相关的研究进展。此外，基于现有研究成果，提出了几个前瞻性内容，可作为未来研究计划的指导方针。
