卧室火灾危险度的双重性模型

本文基于火灾双重性规律的学术思想，构造了室内火灾的确定性和随机性模型，并用微机进行了大量计算．结果表明，此模型能方便地预言在不同的室内家具布置下室内火灾对人的伤害率．

Duality Model of Hazardous State of Room Fires

Following the thought of dual quality of fires proposed before,this article constructs a deterministie and probabilistic model for room fires and sreat ammount of calculation is conducted on thecomputer.In the det6rministic model,it is supped that when smoke temperature reaches 473k or the bottomlevel of the smoke is 1. 5m high,the fire has developed to the state of danger and a threat is posed tohuman lives on the spot. Calculating equations for smoke temperatUre and smoke bottom level are given in the deterministic model. In the prohabilistic model,according to a great amount of material related to fires,probsbilities ofsome kinds of arrangement of furniture in a room and probabilities of a fire due to different causes aregiven.Calculsting results indicate that the deterministic and prohabiliStic model for room fire is practicalin predicting the probability of hazardous state that human lives are exposed to in a fire.
