摘　　要：燃煤过程中产生的氮氧化物是大气污染物的重要组成部分,其大量排放使空气质量恶化,并威胁到土壤、水源和林地。日益严重的环境污染不仅造成巨大的经济损失,而且对人体健康产生很大的影响。中国是一个以煤炭为主要能源的国家,其中50%以上用于发电,因此,火电厂是大气污染物的主要来源。为了减少电厂排放的氮氧化物对环境造成的污染,许多国家都制定了严格的电厂废气排放标准,要求对这些气体浓度进行准确的测量。本文以一氧化氮气体含量检测为研究对象,采用吸收光谱法对一氧化氮气体浓度的监测技术进行系统研究。The nitrogen oxide produced in the process of coal combustion is an important part of the air pollutants, which makes the quality of the air deteriorated and threatens the soil, water and woodland. The increasingly serious environmental pollution no t only caused huge economic losses, but also had a great impact on the health of the human body. China is a country with coal as the main source of energy, more than 50% of which is used for power generation, so thermal power plants are the main source of air pollutants. In order to reduce the environmental pollution caused by nitrogen oxides emitted from power plants, many countries in the world have established strict emission standards for power plants, which require accurate measurement of these gas concentrations. In this paper, the content detection of nitric oxide is the research object, and the monitoring technology of the concentration of nitric oxide by absorption spectroscopy is systematically studied.
