【摘要】 常规的光谱测定方法运用于大气遥测及工业固定污染源排放现场的连续在线监测时会受到一些限制,利用差分吸收光谱法可以在很大程度上解决现场应用上的问题。差分吸收光谱法的应用假定了一些理论上无法直接推导的条件,通过实验验证了这些前提条件的正确性。更多还原

【Abstract】 There are some limitations when general spectroscopy is applied for remote sensing and continuous emission monitoring systems. The differential optical absorption spectroscopy (DOAS) can be used for some field application. Application of DOAS is based on some prior conditions that can’t be directly derived from theory. These prior conditions are validated by the experiment.更多还原
