采用激光诱导荧光（LIF）法测量丙烷扩散火焰中的PAHs（多环芳烃）。各种 PAH 均由 KrF 准分子激光器和由 XeF 准分子激光器泵浦的染料激光器激发。通过测量各种PAHs蒸气的发射光谱发现，随着PAHs碳数的增加，LIF发射光谱中的峰值波长向长波长侧移动。扩散火焰中的PAH的碳原子数是根据发射光谱的峰值波长的数据推测的。证实扩散火焰中PAH的碳原子数随着接近火焰表面而增加。靠近火焰表面的层的最大碳数约为26。
Laser induced fluorescence (LIF) method was applied to the measurement of PAHs (Polycyclic Aromatic Hydrocarbons) in a propane diffusion flame. Various PAHs were excited by a KrF excimer laser and a dye-laser pumped by the XeF excimer laser. By measuring the enission spectra of various PAHs vapors, it was found that the peak wavelength in the emission spectrom of LIF shifted to the longer wavelength side with an increase of PAHs carbon numbers. The carbon numbers of PAHs in a diffusion flame was presumed from the data of peak wavelength of emission spectrum. It was confirmed that the carbon numbers of PAHs in the diffusion flame increased as approaching to the flame surface. The maximum carbon number was about 26 at the layer close to the flame surface.
