中文摘要：
介绍利用同步辐射结合飞行分子束质谱技术,分别检测了加入乙醇前后的汽油在低压预混平面火焰中的燃烧中间物和产物。通过推导,得到两种火焰中的燃烧中间物和产物浓度的具有可比性的算式。借助此算式,比较了标准汽油与乙醇汽油在火焰中的成分差异、温度变化规律,以及几种典型燃烧中间物和产物的空间分布曲线,分析了乙醇对汽油的抗爆性能和排放特性的影响,为日后分析燃烧中间产物和活性基团的分布特性和生成规律以及进一步弄清其燃烧反应动力学机理提供参考。
英文摘要：
With the tunable synchrotron radiation photoionization technique combining molecular-beam sampling mass spectrometry(MBMS),the intermediates and products in premixed gasoline/oxygen flame and gasoline/ethanol/oxygen flame at low pressure were probed.A formula deduced was used to analyze the products and intermediates produced in two types of flame.With the formula,comparison was made among different concentrations of the intermediate and products as well as the spatial profile of temperature in those flames...
