摘　　要：基于分子辐射吸收理论及指数宽带模型,分析了火焰温度和水蒸气浓度的测量原理,建立测量火焰温度和水蒸气浓度的红外光谱的模型.研制了一种新型的火焰温度和水蒸气浓度测量装置,可实现极短脉冲高速火焰的测量,并对煤油喷灯火焰进行了测量实验.Based on the theory of radiation-absorption and exponential wide-band model of gas molecules, the measurement principle of flame temperature and water vapor concentration is given. An infrared spectroscopy measurement model is established and a novel device is developed based on this method that may measure very short pulse flame. Experiments for measuring the kerosene flame with the device show that the temperature and water vapor concentration in kerosene flame are not stable.
