| Abstract: | To improve the analysis ability of residue levels of persistent toxic substances(PTS)in environ-ment,this paper investigated the distribution characteristics of air concentrations of polycyclic aromatic hydro-carbons(PAHs)during the Spring of 2007(January to April)in 4 different functional areas(urban,subur-ban,rural,and remote areas)in and near the Harbin metropolitan by using the fuzzy C-means clustering al-gorithm,and got the cluster centers of different samples and a membership matrix which offered quan... |
