摘要 利用自行组建的开放光程傅里叶变换红外光谱(FTIR)测量系统对大气中的甲烷体进行了连续监测,并将其测量结果与同期参与测量的点式仪器数据进行了对比。结果显示,开放光程FTIR和点式仪器在监测结果上有着良好的相关性(相关系数0.84),前者更能反应出区域内的平均浓度信息,同时也容易受到风速和近地面湍流的影响。 Fourier transform infrared spectroscopy （FTIR） is now widely used in the quantitative analysis of methane in atmosphere. The methane in atmosphere is tested with a open path FTIR system. The measuring results were compared with a point sampling instrument. The results show that they are well coincident with each other, and the open path FTIR is suitable for research work under atmospheric conditions. And it may be interfered with the wind and turbulence near the ground.
