摘　　要：自由基是对流层大气光化学反应的重要组成部分,光化学反应过程中不同的自由基扮演着不同的角色.本文综述了大气中常见的·OH、HO2··、RO·、RO2·、NO3·和环境持久性自由基等自由基的来源,在光化学反应中的作用,以及关键影响因素,展望了未来对于自由基在光化学反应中的研究方向.这对于理解大气氧化性和自由基在光化学反应中的作用机理等核心科学问题具有重要的意义.Free radicals, as a type of essential components of troposphere atmosphere, play different roles in photochemical reaction, owing to their diverse properties, and has gained heightened interests in recent years. The review attempted to summarize the sources of ·OH, HO2·, RO·, RO2·, NO3· and environmental persistent free radicals in the atmosphere, their function in photochemical reactions, as well as the key influencing factors. Besides, the potential promising research directions of free radicals in photochemical reactions were proposed simultaneously. Consequently, the work was of immense significance to gain comprehensive insights into the core scientific issues pertaining to atmospheric oxidative capability and the reaction mechanism of free radicals in photochemical reactions.
