用不同的激光方法对对流燃烧器中二甲醚(DME)和空气的扩散火焰进行了实验研究。利用双宽带旋转相干反斯托克斯拉曼光谱(CARS)、瑞利散射和激光诱导荧光(LIF)对温度、O2浓度和OH浓度进行了定量测量。此外，还利用激光诱导荧光技术测量了甲醛的定性分布。测量的轮廓已经对荧光信号猝灭和玻尔兹曼分布进行了补偿，以获得具有代表性的火焰的定性甲醛轮廓。
A diffusion flame of dimethyl ether (DME) and air in a counterflow burner has been investigated experimentally by means of different laser-based methods. Quantitative measurements of temperature, O2 concentration, and OH concentration have been carried out using dual broadband rotational coherent anti-Stokes Raman Spectroscopy (CARS), Rayleigh scattering and laser-induced fluorescence (LIF). Furthermore a qualitative formaldehyde profile has been measured using LIF. The measured profile has been compensated for fluorescence signal quenching and the Boltzmann distribution to obtain a representative qualitative formaldehyde profile for the flame.
