“死灰复燃”原意比喻失势者重新得势的意思。语见《史记·韩长孺列传》:“蒙狱吏田甲辱安国,安国日:‘死灰独不复燃乎?’”从科学上看,死灰复燃有一定的道理。物质燃烧通常要满足三个条件:必须是可燃性物质,温度要达到着火点,还要有足够的氧气助燃,这三个条件缺一不可。燃烧的微观过程是这样的,加热可燃性物质,使物质中的分子和原子运动加剧,它们之间不断碰撞发热,随着温度升高,分子、原子激发,向外辐射电磁波,低温状态下,物质向外辐射红外线,随着 “Resurgence ” The original meaning metaphor lost power to redefine the meaning. See “Historical Records of South Korea and South Korea Biography:” “Prison prisoner Tianjia insult Anguo, Angolan day: ’Ashes never cease?’” From a scientific point of view, resurgence has some truth. Material combustion usually meets three conditions: it must be flammable substances, the temperature reaches the ignition point, but also enough oxygen combustion, these three conditions are indispensable. Combustion of micro-process is like this, heating flammable substances, substances in the movement of molecules and atoms exacerbated, constantly collision between them fever, with the temperature, molecules, atoms excited, radiating electromagnetic waves, the low temperature state, The material radiates infrared light outwards, with
