The present article provides an overview of the chemical and physical features of haze in China, focusing on the relationship between haze and atmospheric fine particles, and the formation mechanism of haze. It also summarizes several of control technologies and strategies to mitigate the occurrence of haze. The development of instruments and the analysis of measurements of ambient particles and precursor concentrations have provided important information about haze formation. Indeed, the use of new instruments has greatly facilitated current haze research in China. Examples of insightful results include the relationship between fine particles and haze, the chemical compositions and sources of particles, the impacts of the aging process on haze formation, and the application of technologies that control the formation of haze. Based on these results, two relevant issues need to be addressed: understanding the relationship between haze and fine particles and understanding how to control PM2.5.
本文概述了中国霾的化学和物理特征，重点关注霾与大气细颗粒物的关系，以及霾的形成机制。还总结了几种控制技术和策略，以减轻霾的发生。仪器的发展和环境颗粒及前体浓度的测量分析为霾的形成提供了重要信息。实际上，新仪器的使用极大地促进了中国当前的霾研究。有见地的结果示例包括细颗粒物与霾之间的关系、颗粒物的化学成分和来源、老化过程对霾形成的影响，以及控制霾形成技术的应用。基于这些结果，需要解决两个相关问题：理解霾与细颗粒物之间的关系以及理解如何控制 PM2.5。
