摘　　要：在对微粒捕集器的劣化机理分析的基础上,以压降和最大壁面温度两个与性能劣化最相关的参数作为评价指标,运用模糊灰色关联分析方法对于壁面厚度、平均微孔孔径、孔隙率和孔道宽度四个结构参数对劣化性能影响进行分析,获得了相关数据支持,为微粒捕集器性能的进一步优化和改进大气环境质量提供参考依据。In order to effectively analyze structural influence factors of deterioration performance in the diesel particulate filter,and investigate the influence degree of each factor,the deterioration mechanism was analyzed in this paper.The pressure drop and maximum wall temperature were viewed as evaluation parameters of deterioration performance.then,grey relation alanalysis was studied based on grey relational theory,and the data of the influence degree of the main structure parameters on the degradation are obtained.Finally,the result provides a reference for the further optimization of the performance of the particulate trap and the improvement of the atmospheric environmental quality.
