摘要
本文介绍一种燃烧过程中NO浓度的实时测量技术——双光束单光路差分共振吸收法。描述了测量原理和实验装置。实验测定了系统中测量光束和参学光束的吸收截面σ_m和σ_r随温度变化的规律,测量了纯氩气中各种浓度NO混合气。
The differential resonance absorption double-baem technique with single-beam optics is developed for determination of nitric oxide concentration on line real time in combustion environment. Its principles, method and devices are described. The experimental absorption cross sections σ_m and σ_r versus sample temperature are obtained. The results are given for determing sample mixtures of various concentration NO in Ar.
