摘　　要：气体的红外吸收特性是进行气体红外定性定量分析的重要依据。为此,针对4种典型SF6气体分解物SO2、H2S、HF、CO,利用HITRAN2008数据库给出的吸收谱线参数,对其红外吸收特性进行了研究,给出了SO2、H2S、HF、CO 4种气体在波数10～10 000cm^-1范围内吸收谱带的波数区间和最强吸收谱线的中心波数及其峰值吸收系数。另外,分析了SO2和H2S的一段吸收谱受压强和温度的影响,结果表明气体吸收谱线的吸收系数和全线宽随压强的升高而增大;而随温度的升高,气体绝大多数吸收谱线的峰值吸收系数和全线宽会减小,但也存在少数吸收谱线的峰值吸收系数增大的情况。Infrared absorption characteristics of gases are important for infrared gaseous qualitative and quantitative analysis. Consequently, on the basis of HITRAN2008 database, we studied the infrared absorption properties of four typical gas-decomposition products of SF6, including SO2, H2S, HF, and CO, and presented the absorption coefficients, the locations of main absorption bands, the central wave numbers, and the peak absorption coefficients of the strongest absorption lines of four products in the infrared spectral range of 10～10 000 cm^-1. Moreover, we analyzed the influences of pressure and temperature on the absorption spectrum of H2 S and SO~. The results show that the absorption coefficients and the full line widths of the gas absorption lines are increased with pressure; the peak absorption coefficient and the full line width of most of the absorption lines are reduced with increasing temperature, yet few amount of absorption lines have peak absorption coefficients that increase with temperature.
