英文摘要：

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.
