| 摘 要： | 简述了激光诱导偏振光谱技术的测温原理和实验方法,并利用激光诱导偏振光谱技术测量了常压CH4/空气预混火焰的温度分布。该技术灵敏度高,且不受碰撞猝灭的影响,适于诊断各种实际的燃烧过程。通过研究激光能量与信号强度的关系,获得了激光功率密度与信号强度的关系曲线以及实验中的最佳激光功率密度;记录并测量了燃烧场中OH分子A2∑＋-X2Π（0,0）跃迁带中P 1（2）和Q 1（8）两条吸收线的强度,用双线法计算了相应的温度,给出了CH4/空气预混火焰中不同化学配比条件下燃烧场温度的空间分布,实验结果与CARS的测量结果吻合较好。

| Abstract: | The principle of temperature detecting and experimental method of laser induced polarization spectroscopy(LIPS) were introduced,that was applied to determine kinetic temperature of OH in CH4/air premixed flames at atmospheric pressure.This sensitive laser spectroscopy technique is well suited for various real combustion processes,and it not limited by quenching.The relation curve of laser power density and single intensity and optimal laser power density were obtained through investigating the relationship ... |
