气体污染物的红外辐射特性

Infrared Radiative Properties of Gas Pollutants

基于 HITRAN Database给出的谱线参数 ,利用逐线计算方法计算了 SO2 ,CO,N2 O,NO,NO2等气体污染物的红外辐射特性 ,给出了总压为 1atm、温度为 2 96K、波数范围 4 0 0～ 80 0 0内气体污染物的吸收系数分布图。为便于比较 ,同时给出了水蒸汽和二氧化碳气体的吸收系数分布图。

Based on the spectrum data given in HITRAN Database,the infrared radiative properties of gas pollutants,such as SO 2,CO,N 2O,NO and NO 2 are calculated by the line by line method.The absorption coefficient vs wavenumber charts are given for these gas pollutants at a total pressure 1.0 atm,temperature 296 K,and wavenumber from 400 to 8 000.For the sake of comparison,the absorption coefficient vs wavenumber charts of carbon dioxide and steam are also given.
