摘要
本文介绍了一种新型发泡金属材料——发泡镍对冲击波的防护效应。以狗、豚鼠、大鼠作为实验对象,模拟激波管作致伤源,TNT炸药电雷管引爆后致伤。根据致伤后大体解剖及光、电镜观察所见的形态学变化,充分肯定了该材料对冲击波的防护效果。
A new material foamy metallic nickel is used to protect 58 animals from the blast injuries induced by 200g TNT explosion in the imitative shock tube. The animals are divided into 2 groups,the protection group and the blast injury group.The overpressure value varies from 122.5 to 385.0 kPa. All survivals are euthanatized after injury and injection of 3% sodium pentobarbital. The results show, the mortality in the protection group is lower than that in the control group(3:7). The severity of injury in the protection group attenuates by 1 or 2 grades.The mechanism involved in the protection may be that the spongy nickel is constructed by poly-gas holes and their supporting frames.
