国防上用的弹藥,开礦筑路用的炸药包,都是靠爆炸来完成任务的。爆炸的现象,在我们的日常生活中也是时常遇到的,例如汽车、轮船的行驶,就是靠了燃料在内燃机的汽缸内发生爆炸来推动活塞而运转的。在工厂里,往往因为空气中含有某些气体而发生了爆炸。这些都是化学性爆炸。化学性爆炸是怎样产生的呢?为什麽力量这麽大?原来爆炸是化学变化突然的在瞬息间发生,产生大量的气体和大量的热的结果。拿炸药的例子来看,炸药的组成大都是硝基化合物,在
The ammunition used in national defense and the explosives used to open roads are all based on explosions. The phenomenon of explosion is also encountered in our daily life. For example, the driving of automobiles and ships is driven by the explosion of fuel in the cylinder of the internal combustion engine to propel the piston. In factories, explosions often occur because of some gases in the air. These are chemical explosions. How does a chemical explosion occur? Why is it so great? The original explosion was the result of sudden and sudden chemical changes that produced large amounts of gas and a lot of heat. In the case of explosives, the composition of explosives is mostly nitro compounds.
