| 摘 要： | 新型在线光谱测量方法, 如宽带腔增强吸收光谱及可调谐半导体激光吸收光谱技术, 由于其高灵敏度、原位实时以及较好的时间空间分辨率, 被广泛应用于环境排放监测。本文结合实际测量案例, 对腔增强吸收光谱技术在气态亚硝酸、气溶胶消光及可调谐激光在选择性催化还原脱硝中的液膜多参数测量中的应用研究做了总结回顾, 并认为两种测量技术的发展结合, 将为大气化学反应的核心活性物种测量、气溶胶消光参数的准确定量及非均相大气反应动力学测量提供有效的方法。 |

| Abstract: | Novel in-situ spectroscopy methods such as incoherent broad band cavity enhanced absorption spectroscopy (IBBCEAS) and tunable diode laser absorption spectroscopy (TDLAS) have been widely used for ambient emission studies due to their high sensitivity, real time, in-situ and high temporal and spatial resolutions. This work illustrates three real measurements of nitrous acid radical formation, aerosol extinction and multi-parameters of ammonia liquid film. It is conclusively shown that to develop and combine both methods will boost measurement of both atmospheric radical and aerosol extinction, as well as the studies of heterogeneous dynamical chemistry. |
| Keywords: | cavity enhanced absorption spectroscopy HONO aerosol extinction tunable diode laser absorption spectroscopy selective catalytic reduction liquid film |
