摘要
长光程吸收光谱空气质量监测是一种比较成熟的方法,但其在测定的准确性、长期工作的稳定性,数据检测等方面存在不少问题。对该方法的原理、仪器系统组成、运作环境等进行了介绍,论述了产生问题的原因。针对太阳散射光、吸收系数、系统光学部件和气候条件等诸多因素的影响进行了分析评述。
It is mature to monitor air quality by long light-path absorption spectroscopy. But it still has problems in some aspects such as the accurate of monitoring, stability for working long time, and data detection. The principle of this method, the composing of the instrument and the environment are introduced in this paper. The reason of these problems is dissertated. The influence of many factors such as the stray light of the sun, absorption coefficient, optics parts of system and the weather are analyzed as well.
