| 摘 要： | 本文从理论上和试验上系统地探讨了木材炭化后的导电性能与它受热温度和受热时间的关系,阐明了在火灾中木材受热温度越高和木材受热时间越长其所生成木炭的导电性能越好的规律,为火灾调查人员提供了一种通过测定火灾现场残留木炭的电阻值来分析火灾现场温度分布情况,判定火势蔓延方向、起火部位及起火点的快捷有效的方法。

| Abstract: | The paper discusses the relationship between the electric conductivity of the charcoal and its temperature and time be heated on the basis of theory and experiment It clari- fies that in the event of fire ,the higher the wood temperature and the longer the time be heated ,the better the electric con- ductivity of the charcoal It provides effective way for the fire investigator to analyze the temperature distribution in the fire site by determining the resistance value of the charcoal remain- ing there ,and to determine the fire developing direction fire part and fire origin |
