| Abstract: | 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. |
