摘要/Abstract

摘要： 大气中CO2体积分数的日益增加导致全球变暖加剧，这对CO2的高精度检测及其排放的准确监测评估提出了更高的要求。本文搭建了一种基于法布里-珀罗干涉仪的CO2测量系统。在实验室利用样气对该系统进行标定，发现该系统的测量相对误差小于1%，探测精度优于1.43 × 10-6，在30 min 的时间分辨率时探测限为1.24 × 10-6。为进一步验证该系统在大气环境中测量的可行性，将本系统与便携式傅里叶红外光谱仪开展对比测试，在室外进行了14 天的大气CO2体积分数测量。结果证明，两台系统测量的CO2体积分数变化趋势一致，决定系数R2为0.81，表明该系统可为CO2体积分数的在线监测提供一种便携式、高精度的借鉴方案。

Abstract: The increasing volume fraction of CO2 in the atmosphere has led to the intensification of global warming, and at the same time, plasces higher demands on high-precision detection of CO2 and accurate monitoring and assessment of its emissions. In response to this requirement, a measurement system based on Fabry-Perot interferometer was developed for atmospheric CO2 measurement in this paper. The system was calibrated using sample gas in the laboratory, and it was found that the relative error of the system measurement was less than 0.5%, the detection accuracy was better than 1.43 × 10-6, and the system detection limit was 1.24 × 10-6 at a time resolution of 30 minutes. To further verify the feasibility of the system for measurement in actual atmospheric environments, a comparison test between this system and a portable FTIR spectrometer for measring atmospheric CO2 volume fraction was carried out outdoors for 14 days. The results showed that the CO2 volume fraction measured by the two systems exhibited consistent trends with a correlation coefficient R2 of 0.81, indicating that the system can provide a portable and highaccuracy reference solution for online monitoring of atmospheric CO2 volume fraction.
