摘要
相关环境污染信息在太赫兹波段内具有较强的吸收特性，使得利用太赫兹光谱技术探测大气中的污染物成为可能。概述了国内外太赫兹时域光谱技术在气体检测方面的研究历史和发展现状，介绍了不同的气体分子在太赫兹波段的吸收谱，以及对混合气体分子和同素异形体分子的识别。对太赫兹时域光谱技术在气体检测方面的研究方向进行了展望。
Abstract
Due to the strong absorption characteristics of relevant environmental pollution information in the terahertz（THz） range, it is possible to utilize THz spectroscopy technique to detect atmospheric pollutants. The development of THz time-domain spectroscopy （THz-TDS） in gas detecting was briefly covered. The absorption spectrum of some gas molecules in the THz range, identifying gas mixtures and isotopic species were especially discussed. The application future of THz-TDS technique in gas detection was forecasted.
