The two thermodecompo- sition processes were analyzed by Doyle-Ozawa integration method and Achar-Brindley-Sharp-Wendworth differentiation method. Selected from 30 mechanisms, the most probable mechanism function and the kinetic parameters were obtained.

• 采用Doyle- Ozawa积分法和Achar -Brindley- Sharp- Wendworth微分法对两步热分解过程分别进行分析,在30种机理函数中进行筛选,得到了四溴苯酐的两步热分解的最概然机理及动力学特性参数。
