中文摘要：
本文利用同步辐射和分子束取样技术并结合飞行时间质谱仪，分别检测了加入MTBE前后的汽油在氧气中的燃烧产物。通过比较标准汽油与MTBE／汽油在火焰中的成分差异，以及几种典型燃烧产物的空间分布曲线，分析了MTBE对汽油的微观影响机理，为建立燃烧反应动力学模型提供了参考。
英文摘要：
Low pressure premixed gasoline/oxygen flame and gasoline/MTBE/oxygen flame were studied and flame intermediates were identified by molecular-beam sampling mass spectrometry （MBMS） combining with tunable synchrotron radiation photoionization technique. The reaction mechanism of that MTBE effects on combustion is discussed by comparing the differences of products from the two flames mentioned above. The spatial profiles of several typical combustion products are measured. The result is helpful for establishing the kinetic modeling of gasoline/oxygen and gasoline/MTBE/oxygen flames.
