目前,世界各国共有5万件各种类型的核武器,如果核武器在生产、运输、贮藏和服役过程中发生意外爆炸,后果就不堪设想。但自核武器问世50年来,虽然出现了种种意外事故,但从未引起意外的核爆炸。为什么核武器能安全贮运呢?原因是核武器在制造时就采用了周密的安全保障措施。 一是核武器所使用的“引爆”炸药是高能钝感炸药。这种炸药与普通的常规炸药不同,钝感炸药对不正常的环境具有独特的低敏感度。核武器中的钝感炸药,即使受到撞击、枪击、雷击或遇到高温时,也能安然无恙,因而能将意 At present, there are 50,000 different types of nuclear weapons in all countries in the world. If the nuclear weapons explode in an unexpected manner during production, transportation, storage and service, the consequences will be disastrous. However, since the advent of nuclear weapons in the past 50 years, unexpected accidents have been reported but no unexpected nuclear explosion has ever been caused. Why nuclear weapons can be safely stored? The reason is that nuclear weapons used in the manufacture of careful security measures. First, the “detonating” explosives used in nuclear weapons are high-energy insensitive explosives. Unlike ordinary explosives, explosives have a uniquely low sensitivity to an abnormal environment. Insensitive explosives in nuclear weapons can be safe even when hit, shot, struck by lightning or exposed to high temperatures
