摘　　要：把用安德逊级联撞击采样器获得的空气动力学直径为７—１１μｍ的气溶胶粒子镶嵌在ＰＣＤＦ薄膜内。用扫描质子微探针方法对在１８０μｍ×１５０μｍ范围内一群单个气溶胶粒子中１２种元素的含量进行了微区分析，用三维等高线法给出了一群单溶胶粒子中１２种元素的两维分布，并对采样地区的大气污染来源进行了较深人的分析，为大气污染研究提供了新方法。Aerosol samples were collected using Anderson cascade impact samplers and the dispersed single aerosol partiles were embedded in thin PVDF films. A group of single aerosol particles distributed in an area of 180 μm×150μm was analyzed by the scanning proton microprobe(SPM). The distributions of 12 elements in the group were mapped with the three dimensional contour technique. Air pollution sources were then analyzed in some details. It is shown that analysis of the group of single aerosol particles by SPM may become a new approach to the study of air pollution.
