| 摘 要： | 本文利用探针取样法结合同步辐射真空紫外光电离和分子束质谱技术研究了常压下的乙烯扩散火焰.通过测量光电离质谱和光电离效率谱分辨了该火焰中大部分的燃烧中间体及产物;通过改变探针取样位置以及半定量计算得到了其中部分燃烧中间体及产物的摩尔分数曲线.实验结果为探索多环芳烃和烟尘在扩散火焰中形成的最初阶段的反应机理提供了依据.

| Abstract: | An ethylene diffusion flame has been investigated at normal pressure using synchrotron vacuum ultraviolet(VUV) photoionization and molecular-beam mass spectrometry.Most combustion intermediates and products were identified though measurements with photoionization mass spectra and photoionization efficiency spectra.By scanning the sampling position,mole fraction profiles of intermediates and products were measured.The experimental results help study the kinetic model of the primary steps of polycyclic aromat... |
