【摘要】 在用车经过一段时间的使用后,其排放污染物将升高,通过维修保养后可以改善其排放性能。通过利用灰色理论系统对在用车排放污染物的检测数据的分析,来判断在用车排放污染物在车辆维修前后的关系,并通过这种分析判断来检验I/M制度的可行性及可信性。同时对I/M制度和灰色系统理论作了简要介绍,验证了该理论对I/M制度的适用性,从而找出了一种新的对检测数据的分析判断方法。更多还原

【Abstract】 After a period of usage of the in-use vehicle,its emission pollutants will increase,and its emission performance can be improved by maintenance.By the use of grey theory system for in-use vehicle emission pollutant testing data analysis,the relationship of the in-use vehicle emission pollutants before and after maintenance is determined,and through the analysis judgment,the feasibility and credibility of the I /M system are tested.At the same time,the I /M system and grey system theory are briefly introduced,which verify the theory of the I /M system,therefore the applicability of a new kind of the detecting data analysis judgment method is found out.更多还原
