众所周知,火的发明、应用对人类的文明、进步起到巨大的推动作用。然而,人类在用火过程中失去对火的控制,也能造成财产损失和人身伤亡,特别是高层建筑,因火灾造成的损失是极其惊人的。因此,多年来人们就一直积极探索对火灾的早期发现、早期控制,以期把火扑灭在未成灾阶段。
It is well known that the invention and application of fire play a huge role in promoting human civilization and progress. However, when human beings lose control of the fire during their use of fire, they can also cause property damage and personal injury, especially in high-rise buildings. The damage caused by fire is extremely alarming. Therefore, people have been actively exploring the early detection and early control of the fire over many years with a view to putting out the fire at an unmanaged stage.
