摘　　要： 对建筑物中常见的几种可燃物:塑料、硬纸板、布料、三合板、木板等,进行了热解实验,给出了其失重曲线,并导出了热解反应动力学参数———活化能E和频率因子A。建立了基于热解动力学方程和特征浓度的有限空间轰燃预测模型,并给出了计算实例。 The thermal degradation experiments were carried out for some combustibles such as plastic, hardboard, cloth, board, and thipywood which are common in buildings. The weight loss curves were obtained, and the kinetic parameters of activation energy E and frequency factor A were derived. Based on the thermal degradation kinetic equations and the characteristic concentration, the flashover forecast model for limited space was set up. Finally, a case was presented by this model.
