中文摘要：
为了对两个流行的反应动力学机理和一个本组前期发展的修订机理进行全面比较,采用同步辐射真空紫外光电离质谱技术,对甲醇和乙醇富燃（（？）=1.4）低压层流预混火焰进行了试验研究。同时采用这三个机理分别对火焰进行了模拟。结果表明,与前两个机理相比,修订机理的预测精度更高,模拟和试验结果为发展甲醇和乙醇的高温氧化模型提供了参考。
英文摘要：
In order to compare two popular reaction kinetic mechanisms and a revised mechanism thoroughly,an experimental study of the low pressure premixed laminar rich-fuel（φ=1.4） methanol and ethanol flame were performed with the tunable synchrotron VUV（vacuum ultra-violet） photoionization and molecular-beam sampling mass spectrometry.Modelling study was conducted with the three mechanisms.Results showed that better prediction accuracy can be obtained by using the revised mechanism,compared with the other two mechanisms.Modelling and experimental results provide a reference for the development of high temperature oxidation models of methanol and ethanol.
