利用同步辐射和分子束取样技术研究了汽油与氧气低压预混火焰的燃烧产物,得到汽油燃烧火焰中部的光电离飞行时间质谱图以及一些成分的电离能.与文献中的电离能比较后可以确定火焰中产物的具体结构.通过空间分布曲线着重分析了五种有害物质的反应过程,为建立燃烧反应动力学模型奠定了基础.
Synchrotron radiation and molecular beam sampling techniques were used to study the combustion products of low pressure premixed flames of gasoline and oxygen, and the photoionization time of flight spectra and the ionization energies of some components in the middle of the flame were obtained. The comparison with the ionization energy in the literature can be used to determine The specific structure of the product in the flame.The reaction process of five kinds of harmful substances was emphatically analyzed through the spatial distribution curve, which lays the foundation for establishing the combustion reaction kinetic model.
