| 通过试验的方法探讨了喷水灭火残留木炭的导电性能 ,揭示了其随着温度的升高和受热时间的增长而增强的规律 ,为火灾调查人员利用测定喷水灭火残留木炭的电阻值来分析火场温度、判定火势蔓延方向和起火部位提供了一种操作简便、准确可靠的方法。 |
| 英文摘要: |
| The conductivity of water sprayed charcoal residues is studied experimentally in this paper. It has been found that the conductivity of the residues increases with the increase of the temperature and time. By means of measuring the resistance of water sprayed charcoal residues, this paper presents an easy and reliable method for fire investigators to analyze the temperature of fire scene, and to ascertain the direction of fire spread and the original location of fire. |
