美国国防部的专家们又有了新任务,研制能够既镇压群众骚乱又不会造成人员伤亡的武器,其中有用高密度像胶制成的子弹,被这种子弹击中的人会暂时失去知觉。泡沫喷射器的研制可能是受到好莱坞幻想片的启发,它可以喷射出粘稠的泡沫,使人行动困难。如今对这种泡沫器进行了改进,原因是这种泡沫一旦进入呼吸道,可能造成致命的后果。另外还在研制两种不同作用的池沫:一种是在空气中能够很快凝固的泡沫,用它来封锁大门口,禁止人们出入;另一种是可以在地面上铺上一层很滑的涂层的泡沫,人和汽车都无法在上面行走。
Experts in the U.S. Department of Defense have renewed their task of developing weapons capable of suppressing both civil commotion and casualties, including the use of bullets made of high-density rubber that temporarily lose consciousness when hit by such bullets . Bubble jet development may be inspired by the Hollywood fantasy film, it can spray a thick foam, making it difficult for people to move. This foam has now been improved because once it enters the respiratory tract, it can have fatal consequences. In addition, two different types of foam cells are being developed: one is a foam that rapidly solidifies in the air, which is used to block the entrance and prohibit people from entering or exiting. The other is to have a very smooth layer of foam on the ground The coated foam, people and cars are unable to walk on it.
