摘　　要：按照加速模拟工况检测法(ASM)、双怠速检测法和自由加速检测法,对近10万辆在用汽车排气污染物检测数据进行了大样本数据分类统计.对ASM检测结果数据,以不同阶段的汽车排放国家标准执行日期作为使用年限区间分类规则,参考行业标准排放限值,系统分析了不合格率及变化趋势、平均值及群体劣化趋势.The large sample data classification statistics of exhaust pollutants test data from about 100, 000 in-use vehicles were conducted according to acceleration simulation mode （ASM）, two-speed idle conditions and free acceleration conditions. Aiming at the test data obtained from ASM, the imple- mentation date of different stages national vehicle emissions standards was regarded as the useful life interval classification rules. Referencing to the emission limits from the industry standard, the non- conforming rate and trends, the mean and group deterioration trends of the test data were analyzed systematically. Apart from the establishment of regional in-use vehicles exhaust emission limits stand- ard, the analysis could provide useful methods not only for extracting a lot of valuable information from in-use vehicles exhaust pollutant test data but also for determining exhaust pollutants character- istics of high-emission vehicles accurately.
