利用手持技术探究建筑火灾逃生策略的合理性--测量氧气含量、二氧化碳浓度和温度的变化

Rationality of Building Fire Escape Strategies:Determination Changes of Oxygen Content,Carbon Dioxide Concentration and Temperature by Hand-Held Technology

以"蜡烛在亚克力容器中的燃烧"作为建筑火灾逃生通道模拟系统,利用手持技术实时测量亚克力容器内不同高度的氧气含量、二氧化碳浓度、温度的变化,并呈现直观可视的曲线图像。通过对几种表征曲线所负载信息的深入分析,有效解释了建筑火灾发生时关键逃生策略的合理性,深化中小学阶段学生对"燃烧与灭火"相关知识的理解,并有助于提高学生的消防意识及逃生技能。

Taking＂burning of candles in an Acrylic container＂as a building fire simulation system and using hand-held technology,this paper presented the real-time changes of oxygen content,carbon dioxide concentration and temperature at different heights of the Acrylic container,and presented the corresponding curves.Through the in-depth analysis of the information contained in the curves,the rationality of key escape strategies in the event of building fire was effectively explained,intensifying the understanding of＂combustion and fire suppression＂of primary and high school students and contributing to improving people＇s fire awareness and survival skills in real life.
