炮弹、子弹看似冷酷无情,其实它们有时也很拉风——战争是恐怖的,是丑恶的,但战争的恐怖和丑恶也促使人们绞尽脑汁,创造出制胜的巧妙武器,进而促使了科技的快速发展。下面一些巧妙的设计正是应战争的需要而生的。酒桶炸弹1975年越南战争期间,5架美军飞机曾飞抵越南上空,投下了100多枚酒桶样的炸弹。奇怪的是,这些炸弹途中却展开了一个个小降落伞,酒桶吊在小降落伞下面,桶 Shells and bullets are seemingly cruel and in fact they are sometimes very windy - the war is horrifying and ugly, but the horrors and ugliness of the war also motivate people to create the clever weapon of victory that in turn leads to the advancement of science and technology The rapid development. Here are some ingenious designs that were born to meet the needs of the war.
