| 摘 要： | 应用遥感FTIR在不同高度下,测定大气中的有毒易挥发有机化合物(VOCs)——甲苯,正己烷和丙酮的浓度。并对相同的高度下,测量的精度做了研究。当高度为0.61 m时,所测得的气体的浓度值最大,而当仪器高度为0.36和0.86 m时,测得的浓度则较低。实验结果表明,在不同的高度下VOCs的挥发是不同的。

| Abstract: | Open-path remote sensing FTIR was utilized in this paper for monitoring air toxic VOCs, such as toluene, hexane and acetone. The influence of IR beam height on the recorded absorbencies and the estimating precision of FTIR monitoring was discussed. When the optical path was 0.61 m above the ground, the measured concentrations of the desired gases were higher than those measured at 0.36 or 0.86 m of optical path. Results showed that the height of the optical path plays a significant role in the measured concentrations. |
