| 摘 要： | 建筑火灾中轰燃现象是一种典型的突变过程。本文利用数学方法推导出轰燃的突变动力学，首先给出基于能量平衡方程的轰燃模型并构建其突变簇方程，然后讨论系统控制因子和实际工况之间的关系。结果发现建筑火灾中轰燃现象的突变形式是燕尾突变。

| Abstract: | By physical observation, flashover in build-ing fires is a suggestive of a catastrophe process. Inthis paper, catastrophe dynamics of flashover is investi-gated by mathematical method. Firstly, a model offlashover based on energy balance equation is estab-lished. Secondly, the corresponding relationship be-tween system control variables and operating conditionsis discussed. The results indicate that flashover inbuilding fires is in essence a phenomenon of swallowtailcatastrophe. |
