汽车排放物各成分间关系的灰色关联分析

Gray relative analysis of the relations of automobile emissions

汽车排放污染物是发动机混合气燃烧反应的产物 ,由于汽油机工况和反应的复杂性 ,各排放污染物成分间的关系呈非线性 ,用传统的回归分析方法存在很大的局限性。文章用灰色理论计算出一般工况下汽车排放污染物各成分浓度与 CO浓度间的灰色关联度 ,并对计算结果作了相应的分析 。

Automobile emissions are the burning results of the mixture gases in the combustion chamber of engine. Because of the complexity of burning,the relations between the ingredients of automobile emissions are non linear and the conventional regression analysis method is very limited. In this paper,the gray relative degrees of the ingredients of automobile emissions are calculated using the gray theory and the result analyzed correspondingly. The presented method provides a new way for the comprehensive analysis of automobile emissions.
