| 摘 要： | 以激波管作为加栽工具、利用研制的瞬态谱测试技术，对苯在冲击波作用下的快速反应光谱及微观机理进行研究．研究表明：苯在冲击条件下，分子高温分解反应是从C—H键开始的，而不是C—C键．C—H键在温度达到一定值时首先断裂，进行C6H6＋（M）→C6H5＋H＋（M）的反应．此外，苯在冲击条件下及易发生高温分解反应，对此提出了一种防止杂色光误触发的新方法．

| Abstract: | The fast reaction spectrum and micro-mechanism of benzene has been studied in shock tube with transient spectroscopic technique. The results indicate that the thermal decomposition of benzene under high-temperature condition is C -H bond for the initiation reaction,not C -C bond. The dissociation is C -H bond scission C6H6 ＋ （ M）→C6H5 ＋ H ＋ （M） for the initiation reaction. In addition, on account of the pyrolysis of benzene easily driven under shock compression, a new method is introduced to prevent advance trigger from heterochromatic light. |
