摘要: 近年来在大气污染的防治工作中,柴油车污染防治的重要性日渐凸显.本文通过测试和文献检索等方法收集了97组与柴油车排放颗粒物无机元素排放有关的数据,采用k-means均值聚类分析的方法对数据进行分类并对分类结果进行分析,得出柴油车无机元素排放占颗粒物比例的大致区间为:Si(0—4.62%)、Al(0—1.53%)、Ca(0—4.09%)、Na(0—2.61%)、Mg(0—2.68%)、K(0—0.85%)、Fe(0—3.4%)、Zn(0—0.54%)、Cu(0—1.49%)、Ni(0—0.06%),且所得无机元素的排放区间的置信水平均大于94%.同时得到的柴油车排放颗粒物无机元素分析结果,可以为后续柴油车排放颗粒物无机元素数据分析以及相关污染治理提供参考,进而促进我国大气环境质量的改善、更好地保障人们身体健康.Abstract: In recent years, the importance of diesel vehicle pollution has become increasingly prominent in air quality control in China. Ninety-seven data related to the emission of inorganic elements from DPM (Diesel Particulate Matter) from our own experiments and also previous references, were collected and classified by k-means cluster analysis. The results showed that the approximate range of inorganic element in DPM were as follow: Si (0-4.62%), Al (0-1.53%), Ca(0-4.09%), Na(0-2.61%), Mg (0-2.68%), K (0- 0.85%), Fe (0-3.4%), Zn (0-0.54%), Cu (0-1.49%), and Ni (0-0.06%).The confidence level of the obtained inorganic element variation range was more than 94%. Our results can be helpful for related future studies of vehicle emission control and health impact assessment.
