摘要
利用连续波窄带可调谐钛宝石激光器和长光程吸收池测量了９１７～９４５ｎｍ６０余条水汽吸收线的强度和空气加宽系数。线强度测量精度优于４％，加宽系数测量精度优于６％。线强度结果和Ｃｈｅｖｉｌａｒｄ等的测量结果比较，比值为０．９８６±０．０６８５，符合得较好。空气加宽系数和Ｈｉｔｒａｎ－９２数据库比较，比值为０．９０６±０．１６４。
Water vapor high resolution spectroscopy were recorded with a cw narrow linewidth Ti∶Sapphire laser and a long pass absorption cell in 917～945 nm wavelength range. Measurements were made of line strengths with 4% uncertainty and air broadening coefficients with 6% uncertainty of 60 water absorption lines. Compared with Chevillard′s line strengths data, the agreement is good with average ratios of 0.0986±0.0685. However, the difference of air broadening coefficients is obvious between Hitran 92 database and ours, with average ratios of 0.906±0.164.
