运用网络模型（networks）对火灾在房间之间的蔓延过程进行了分析；计算不同条件下火灾沿不同路径蔓延的概率和时间，找出其中危险的因素；通过加强安全措施，对火灾蔓延过程进行了有效的控制。结果表明，应用网络模型来分析火灾在房间之间的蔓延过程，可对于蔓延的可能性和危险性作出了较好的预测。

This paper introduces the Networks model to analyze the process of fire spread among the rooms. It finds out the dangerous factor through calculating the probability and time of defferent fire spread path under defferent conditions. The process of fire spread can be controled effecting by strengthening the safety precautions. Results indicate the Networks model can predict the possibility and hazard of fire spread among the rooms.
