摘　　要：论文以我国的轻型汽油车为重点研究对象,并依据我国的测量标准技术JJF 1059.1-2012《测量不确定度评定与表示》规范,依据《GB 18352.6-2016轻型汽车污染物排放限值及测量方法(中国第六阶段)》进行了I型试验,通过对引起测试结果不定性改变的主要因素进行了分析和计算,从而判断汽车所排出的NOx排放量的测量不确定度。根据结果可知,在保持测量过程统一性和标准物质质量的条件下,对NOx排放检测结果的置信性影响是很大的。This paper focuses on light gasoline vehicles in China,and according to China's measurement standard technology JJF 1059.1-2012"Evaluation and Representation of Measurement Uncertainty",and according to GB 18352.6-2016 Pollutant Emission Limits and Measurement Methods for Light Vehicles(China Stage 6)",the measurement uncertainty of NOx emissions emitted by automobiles is judged by analyzing and calculating the main factors causing the qualitative change of test results.According to the results,the confi dence in the NOx emission test results is greatly aff ected while maintaining the uniformity of the measurement process and the quality of the reference materials.
