摘　　要：利用激光闪光光解技术对不同条件下苯与亚硝酸水溶液的交叉反应机理进行研究,考察了瞬态物种的生长与衰减等行为;得到了C6H6OH加合物,C6H6NO+π络合物等中间产物,并结合其光解产物的GC/MS分析,对其可能的反应机理进行了探讨,得出了一些微观反应速率常数.The cross-reaction microscopic mechanism of aqueous benzene with nitrous acid in dilute solutions under different conditions was studied by laser flash photolysis. The main intermediate products such as C_~6 H_~6 -OH adduct and C_~6 H_~6 -NO^+ πcomplex were found and the build-up/decay trends of several transient species as well as the reaction mechanism were investigated.Several reaction rate constants were calculated.
