摘　　要：烯烃臭氧化反应是大气对流层中发生的极为重要的反应。Criegee中间体作为烯烃臭氧化过程的关键中间体,其化学反应是大气OH自由基、有机酸、硫酸以及硝酸盐等物质的重要来源,因而受到充分的关注。因Criegee中间体寿命短暂,其检测方法很少。目前如何检测该物质是颇为热门的难题。总结了最近几年Criegee中间体测量方面的研究成果,包括各种检测方法及其特点。简单地将这些方法分为直接检测和间接检测两大类。最后比较了这些检测方法并对未来的研究方向作了展望。Ozonolysis of alkenes is extremely important in the troposphere.Criegee intermediates（CIs） are the key intermediates in the ozonolysis of alkenes.The reactions of CIs are important sources of atmospheric OH radicals,organic acids,sulfuric acid,and nitrate etc.There are seldom CIs detection methods due to CIs’ short-life time.Currently,how to detect CIs is a quite hot issue.The research progress of CIs measure including a variety of detection methods and their characteristics in recent years was summarized.These methods were briefly divided into direct and indirect detection methods.Finally,these methods were compared and the directions for future research were prospected.
