碳排放在线检测中CO2示值误差测得值的不确定度分析

Uncertainty Analysis of the Measurement Result of CO2 Indication Error in On-line Detection of Carbon Emissions

文章分析了碳排放在线检测中二氧化碳示值误差测得值的不确定度,充分考虑了重复测量的标准偏差、测量仪器的分辨力的量化误差、标准气体的额定值不确定度以及二氧化碳气源的流量波动等对二氧化碳示值误差测得值的影响,分析出二氧化碳示值误差测得值的相对扩展不确定度为0.8%。

This paper analyzed the uncertainty of carbon dioxide indication error in on - line carbon emission measurement. The influence of standard deviation of repeated measurement,quantification error of resolution of measuring instrument,uncertainty of standard gas rating and flow fluctuation of carbon dioxide gas source on measurement results of carbon dioxide indication error was also fully considered.And the synthetic extended uncertainty of carbon dioxide concentration indication error was 0.8%.
