当一颗炮弹爆炸的碎片朝你飞来时,你是用装甲钢板还是用装满水的塑料袋来作掩体保护自己呢?你很可能选择装甲钢板。但是按科学家现在的看法,你最好是用装满水和气泡的聚乙烯袋作掩体。这是一位英国爆破专家理约翰·帕克斯在经过严格的试验后作出的结论。事情发生在1993年,当时,在格拉斯哥要拆除两座大楼,许多人站在远处看热闹,他们对用爆破方法拆除楼房毫无戒备,以为现在的爆破技术对四周不会造成任何危险。谁知爆破后,雨点般的碎片落在了一些旁观者的身上,还有一位妇女被砸死。爆破后的滚滚烟尘也给四周造成严重污染。这件事使帕克斯急切想找到一种防止爆炸碎片伤人的最佳办
When an exploding fragment of an artillery projectile comes to you, do you protect yourself using armored steel or plastic bags filled with water? You probably choose armor plates. But according to the scientists now, you’d better use a polyethylene bag filled with water and air bubbles as a bunker. This is the conclusion made by John Bucks, a British blasting expert, after rigorous testing. It happened in 1993, when two buildings were to be dismantled in Glasgow and many were standing in the distance watching the show. They were unprepared for the demolition of buildings by the blast method, thinking that the current blasting technology would not cause any danger to all four. Surprisingly, after the blast, the raindrops fell on bystanders and a woman was killed. After the blast of rolling dust also caused serious pollution around. Parker was eager to find the best way to prevent people from exploding
