| 摘 要： | 本实验测定了兰州西固地区气溶胶中13种元素含量。用主因子分析(PFA)和目标转移因子分析(TTFA)法对数据进行处理,分辨出细粒子六个源和粗粒子四个源,并计算出各源对总悬浮颗粒物(TSP)的贡献,发现煤飞灰是当地的一个主要污染源。

| Abstract: | The concentrations of thirteen elements were determined by X-ray fluorescence analysis for aerosol samples collected from Xigu area, Lanzhou during winter time. The data was divided into two subsets: those for fine fraction and those for coarse fraction. The two separate subsets of data were analysed using principal factor analysis and target transformation factor analysis techniques. Six sources of fine fraction and four sources of coarse fraction have been identified. Of those, fly ash is the major pollutant source in the area. |
