科幻小说家描述了一种发射能量波把人击倒的武器。这种武器只是让人失去作战能力,并不会直接把人杀死。冷战时期,苏联曾研制出一种次声波武器。据说次声波武器能够穿透15厘米厚的混凝土和坦克钢板,人即使躲到防空洞或钻进坦克的“肚子”里,一样难逃厄运。真是可怕的武器!美国国防部(五角大楼)一直也在研制声波武器,虽然没有上述的次声波武器那 A science fiction novelist describes a weapon that launches a wave of energy that knocks people down. Such weapons simply deprive them of combat capability and do not kill people directly. During the Cold War, the Soviet Union developed an infrasonic weapon.
