摘　　要：文章在对微粒捕集器的劣化机理分析的基础上,以与性能劣化最相关的参数压降作为评价指标,运用模糊灰色关联分析方法对排气流量、排气氧浓度、微波功率、催化添加剂的质量浓度和灰烬沉积量五个运行参数对劣化性能影响进行分析,为微粒捕集器性能的进一步优化提供参考依据。In order to effectively analyze running parameter influence factors of deterioration performance in the diesel particulate filter, the deterioration mechanism was analyzed in this paper. The pressure drop was viewed as evaluation parameter of deterioration performance. And then, grey relation analysis was studied based on grey relational theory. Finally,the result provides a reference for the further optimization of the performance of the particulate trap.
