水蒸气分子光谱数据在航天科学、大气科学、天体物理以及热能动力工程中有着广泛的应用。本文以最新的高分辨率高温燃气光谱数据库HITEMP为基础,通过合理的外推,计算得到300~3 000 K的温度范围内水蒸气谱带模型参数:平均吸收系数、谱线密度、谱线半宽,建立了比1973年NASA发布的数据更新、更详细的模型参数表。以本文的模型参数表为基础,采用统计谱带模型计算了各种光学路径下的发射光谱,其结果与实验值符合很好。

Spectral data of water vapor molecules have been widely used in the fields of aerospace science, atmospheric science, astrophysics, thermal energy and power engineering. On the basis of the newest high-resolution high-temperature gas spectral data base HITEMP and by way of a rational extrapolation obtained were the water vapor spectral band-model parameters in the 300 - 3000 K temperature range. The latter include an average absorption factor, spectral line density, spectral line half-width. As a result, set up was a more up-to-date and detailed model parameter table than that promulgated by NASA in 1973. With the model parameter table serving as a basis the authors have through the use of a statistical spectral band model calculated emission spectra under various optical paths, which have been found to be in very good agreement with experimental values
