本文应用质子荧光分析(PIXE)和分级采样的方法阐明北京冬季气溶胶的化学成分和特征。采样是使用单孔冲击式分级气溶胶采样器,试样先在中国科学院高能所进行了分析,后来又在美国佛罗里达州塔拉哈西市元素分析公司进行了分析核对。
In this paper, the chemical composition and characteristics of Beijing winter aerosol are elucidated by using proton fluorescent analysis (PIXE) and grading sampling. Sampling is the use of single-hole impact graded aerosol sampler, the sample was first analyzed at the Institute of High Energy, Chinese Academy of Sciences, and later in the United States, Tallahassee, the United States conducted an analysis of elemental analysis.
