太赫兹波具有独特的性质和应用，却存在大气衰减等物理上的限制。由于太赫兹波在大气传输中主要衰减来自水蒸汽，文中采用太赫兹时域光谱技术，通过构建不同行程的太赫兹时域光谱系统(0.5 m、1 m、2 m、3 m)，在0.1~2.0 THz频率范围内，分别对不同湿度的空气进行太赫兹时域光谱测量，获得了25个水吸收峰和10个太赫兹窗口。结果表明：随着传输行程或湿度的增加，吸收谱带被展宽、太赫兹窗口被压缩，为超宽谱太赫兹波的潜在应用提供依据。

Terahertz waves have unique properties and applications, but there are physical limitations such as atmospheric attenuation and so on. Since the main attenuation of terahertz transmission in the atmosphere comes from water vapor, terahertz time-domain spectroscopy was used to conduct terahertz time-domain spectroscopy measurements in different air humidity at the frequency range of 0.1- 2.0 THz by building terahertz time-domain spectroscopy system with different stroke (0.5 m, 1 m, 2 m, 3 m), respectively. 25 absorption of water and 10 windows of THz waves were obtained. The results show that:with the increase of transmission itinerary or humidity, absorption band is broadened and terahertz window is compressed. The study provides the basis for the potential applications of ultra-broadband terahertz waves.
