气溶胶质谱仪在对气溶胶颗粒的监测过程中会产生大量单颗粒的化学成分和粒径信息,基于这些质谱数据能够推测颗粒的来源。而对气溶胶来源的分析,很大程度上是由颗粒的种类决定的,故对海量数据的分类就成为不可忽略的步骤。针对气溶胶质谱仪采集到的数据,概述了用于气溶胶分类的多种方法的理论核心、分类步骤及各自的优缺点等。据此可为今后气溶胶分类方法的研究提供建设性意见。
Aerosol mass spectrometry produces large amounts of single-particle chemical composition and particle size information during aerosol particle monitoring, from which one can infer the origin of the particles. The analysis of the source of aerosols, largely determined by the type of particles, so the classification of mass data has become a non-negligible steps. For the data collected by the aerosol mass spectrometer, the theoretical core of the various methods used to classify aerosols, the classification procedures and their respective advantages and disadvantages are outlined. According to this, we can provide constructive suggestions for the future research of aerosol classification methods.
