传统火炮的原理及局限性火药是我国隋唐时期由炼丹师偶然间发明的,距今已有一千多年了.后来,火药应用到军事上,发展成各种各样的炸弹和火炮.传统火炮的基本工作原理是利用火药在极短时间内迅速燃烧,使空气急剧膨胀,从而推动炮弹(或子弹)高速前进.我们知道,物体运动就具有动能,可以对外做功.如果物体的动能足够大,就会有很大的破坏作用,将目标物体摧毁,造成人员伤亡,火炮从出现到现在的700多年间,各国的研究人员都在极力想办
The principle and limitations of traditional artillery Gunpowder was invented by the Alchemist in our country during the Sui and Tang Dynasties, dating back more than a thousand years. Later, the gunpowder was applied to the military and developed into a variety of bombs and artillery. The basic principle of artillery is the use of gunpowder rapidly burning in a very short period of time, so that the rapid expansion of air, and thus promote the projectile (or bullet) high-speed advancement.We know that object movement has kinetic energy, can work outside.If the object kinetic energy is large enough , There will be a great damaging effect, which will destroy the target object and cause casualties. For more than 700 years since the emergence of artillery, researchers all over the world are trying their best
