摘　　要：从固定源细颗粒物采样方法、细颗粒物分级捕集技术与颗粒物样品处理分析技术入手,分析和探讨了国内外固定源细颗粒物监测技术的研究现状,指出了相关细颗粒物监测技术与分析方法的优缺点,提出了针对固定源细颗粒物监测技术与设备配置的研究思路与建议。基于源环境的固定源细颗粒物直接采样法广泛应用于日常监测,而基于大气环境的固定源细颗粒物稀释通道间接采用方法多应用于科学研究,且其烟气稀释比对颗粒物粒数浓度有显著影响。颗粒物惯性撞击式分级切割采样器控制简单,无复杂清洗过程,并可适用于国内大部分烟尘环境。细颗粒物样品因气溶胶占较大比重,不宜烘干处理。Starting from the monitoring method and the size separated sampling technology of fine particulate matters emitted from stationary source and particulate matter sample processing and analysis technology,the research status of the monitoring technology of fine particulate matters emitted from stationary source at home and abroad were analyzed and discussed. The advantages and disadvantages of the monitoring technique and analysis method of fine particulate matters were pointed out.Research ideas and suggestions on monitoring technology and equipment configuration of fine particulate matters emitted from stationary source were proposed. The direct sampling method of fine particulate matter based on source environment was widely used in daily monitoring. But the indirect sampling method of the fixed source dilution channel based on atmospheric environment was used for scientific research, and the flue gas dilution ratio had a significant effect on the particle number concentration. Particle inertia impact type grading cutting sampler was easy to control, no complicated cleaning processes, and can be applied to most domestic dust environment. Fine particulate matter sample due to the larger proportion of aerosols,should not be drying treated.
