【Abstract】 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.更多还原
