中文摘要：
工业革命以来,温室效应引起的全球气候变迁问题越来越受到人们的关注。人类活动相关的主要温室气体是CO2,CH4,N2O和CO,对其浓度进行连续测量,获取浓度随时间的变化规律对大气环境科学具有重要意义。使用多次反射池FTIR系统在浙江地区对这四种气体进行了监测,通过对测量的气体吸收光谱进行光谱定量分析,获取了待测组分的浓度信息,并对其变化规律进行了分析。同时对仪器的性能进行了检测,结果表明,多次反射池FTIR是进行环境气体监测的一种快速有效直接的监测手段。
英文摘要：
Since the industrial revolution,global climate change problems caused by greenhouse effect are getting more and more concern.CO2,CH4,N2O and CO related to human activities are main greenhouse gases in the atmosphere.It is of important significance for atmospheric environmental science to access greenhouse gases′ concentration variation with time.CO2,CH4,N2O and CO are continuously monitored by using multi-reflected white cell Fourier transform infrared（FTIR）spectrometer at a specific site in Zhejiang.The concentration of components information is obtained by measuring gas atmospheric absorption spectra and concentration variation is also analyzed.In the meantime the performance of instrument is tested and the results show that multi-reflected FTIR of environmental gases monitoring is a fast,direct and effective means of monitoring.
