摘要
针对环境空气颗粒物浓度测量中的测不准、难溯源的难题,紧密结合国家标准以及国家计量发展规划对环境空气中气溶胶颗粒物质量浓度计量溯源的需求,对颗粒物采样、颗粒物粒径分离和颗粒物质量浓度测量等关键技术,全方位系统地叙述了关键技术中国家标准物质、计量标准装置、技术国际等效性和国家标准技术攻关的相关情况,立体搭建了环境空气颗粒物溯源体系。保障了环境空气颗粒物监测数据的准确可靠,以及与国际同类监测数据的一致性,建立了我国环境空气颗粒物监测溯源基准。
In view of the difficulties of uncertainty and traceability in the measurement of ambient air particle concentration, and in close combination with the requirements of national standards and Metrological Development Plans for measurement and traceability of aerosol particle mass concentration, the key technologies such as particle sampling, particle size separation and particle mass concentration measurement are focused on, and the metrological traceability system for ambient air particles has been established through scientific and technological research, which is carried out systematically on national reference materials, measurement standard devices, international equivalence of technologies and national standards. The project research ensures the accuracy and reliability of the monitoring data of ambient air particles, the consistency with international monitoring data and the traceability standard ’s establishment in the field in China.
