摘要
根据大气中污染气体SO_2和NO_2在紫外波段的光谱吸收特性,利用差分吸收光谱技术(DOAS),研制了大气环境质量在线连续检测系统。本文详细介绍了该系统的检测原理和设计。系统能快速、实时、高精度地监测大气中痕量污染气体的浓度,为环境监测和保护提供可靠的数据。对比试验表明,该系统设计合理,能满足空气质量在线连续监测的要求。
An environmental air quality on-line continuous monitoring system based on the technology of differential optical absorption spectroscopy （DOAS） was designed for monitoring pollution gases in air with absorption spectra in UV region. The measurement principle and design of the system are described in detail. By using DOAS technology, the concentrations of trace pollution gases in air can be detected rapidly and accurately in real-time to provide reliable data for air protection. Comparative experiments showed that the design of the system is reasonable and the system can meet the requirement of air quality on-line continuous monitoring.
