摘要: 机动车排放的超细颗粒物是大气污染的主要来源之一, 具有高的数浓度和表面积, 对其进行准确在线监测是 机动车排放评估与控制措施制定的重要前提。随着欧盟和中国相继在机动车排放标准中增加颗粒物粒子数量 (PN) 控 制指标, 对在线监测技术的要求也日益提高。目前, 对机动车排放的超细颗粒物数量的测量主要采用扩散荷电法和凝 结核粒子计数法, 对其粒径谱分布的测量主要采用空气动力学和电迁移率分级方法。综述了国内外在机动车排放超 细颗粒物在线监测技术方面的研究现状, 重点介绍了主要发展的几种测量技术及仪器的原理、特点和应用状况, 并对 其未来发展进行了展望。

Abstract: Ultra-fine particles emitted by motor vehicles which have high number concentration and surface area, are one of the main sources of air pollution, . Accurate on-line monitoring is of significance for vehicle emission assessment and control measures. With the addition of particle number (PN) control index in vehicle emission standards in EU and China, the requirements of on-line monitoring technology are also increasing. At present, diffusion charging method and condensation nuclear particle count method are mainly used to measure the number of ultra-fine particles emitted by motor vehicles, and aerodynamics and electro-migration classification methods are mainly used to measure the particle size distribution. The research status of on-line monitoring technology of ultra-fine particles emitted by motor vehicles at home and abroad is summarized, the principle, characteristics and application status of several main developed measurement technologies and instruments are mainly introduced, and the future development of the technologies is prospected.
