- 摘要：基于粗集理论(RS)对于不确定性问题的近似分类的思想和方法, 通过计算大气污染源排放的元素组成的差异程度与大气颗粒物样本中元素含量的分类关系, 用排放源对于大气颗粒物元素含量的有效程度为标准来评价排放源的重要性.进行了实例分析计算并与其它几种源解析法结果比较表明:不同源解析法给出的主要排放源的重要性排序是一致的.
- Abstract：Based on the approximation classification thoughts and method of rough sets theory for uncertainty information,calculation were carried out to study the classification relation betwwen the different extents of element components of atmospheric pollution sources and the element contents of atmospheric particulate samples.Importance evaluation of source was performed using the effective extent of source as standard for the element content of atmospheric particulate.Analyses of cases and comparisons with other source apportionments suggested that the orders of importance of main atmospheric pollutant sources show no difference using different sources apportionment.
