| 摘 要： | 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。

| Abstract: | Method of aerosol clustering was introduced on basis of literature reviews.Purpose of the research is to trace the sources of aerosol particles,which can be inferred from the mass spectrum data.The source of the particles can also be determined to some degree by the classification of particles,thus aerosol particles clustering is necessary for the enormous number of mass spectrum data about single particle's chemical compositions as well as aerodynamic diameter.Core theories,classification procedures and pros and cons of the method were summarized for the aerosol mass spectrometer. |
