摘要
本文介绍了用红外激光光声光谱方法测量柴油机尾气中的NO,并与红外激光吸收光谱法及萨茨曼湿化学法测量结果进行了比较,结论基本一致.同时,还介绍了可以提高灵敏度的无端窗光声池.
The NO concentration in diesel engine exhaust gas was measured by infrared laser opto-acoustic spectrometry. Measured results were compared with those obtained by infrared laser absorption spectrometry and wet chemistry analysis. A high sensitive window-free opto-acoustic cell was introduced to improve the measurement sensitivity.
