摘　　要：通过搭建碳排放连续在线监测实验平台,模拟分析二氧化碳排放连续在线监测过程。依据JJF 1059.1-2012《测量不确定度评定与表示》和JJG 640-2016《差压式流量计》等技术规范,建立碳排放量测量结果的不确定度评定数学模型,全面地分析测量不确定度来源,并对测量结果进行不确定度评定。结果表明:碳排放连续在线监测实验平台的扩展相对不确定度为5.86%,包含因子k=2,置信水平为95%,测量结果的不确定度主要来源于环境温度引入的系统误差。Through the establishment of carbon emission continuous online monitoring experimental platform,the continuous online monitoring process of carbon dioxide emission was simulated and analyzed.According to JJF 1059.1-2012 Evaluation and expression of uncertainty in measuirement and JJG 640-2016 Differential pressure flowmeters,the uncertainty evaluation mathematical model of carbon emission measurement results was established,the source of measurement uncertainty was comprehensively analyzed,and the uncertainty evaluation of measurement results was carried out.The results show that the expanded relative uncertainty of the experimental platform for continuous on-line monitoring of carbon emissions is 5.86%,the coverage factor is k=2,and the confidence level is 95%.The uncertainty of the measurement results mainly comes from the system error introduced by the ambient temperature.
