摘要
实验动物为成年杂种狗16只,其中实验(防护)组7只,对照组9只。用BST—Ⅰ型生物激波管和导弹战斗部静爆致伤,前者反射超压为388.4kPa～399.7kPa,后者离爆心4.5m处入射超压为390kPa～459kPa。结果表明防护组的死亡率比对照组低,肺损伤程度比对照组也要轻1—2个等级。结果提示复合材料对冲击伤有较好的防护效果。
Sixteen adult mongrel dogs weighing 10.2-14-2 kg were used in this study. They were divided into 2 groups. One of which was composed of 7 dogs in the protection group, while the other, the control group, included 9 dogs. The blast injury was induced by BST - 1 shock tube and explosion of combat parts of guided missiles. The reflected overpressure values varied from 388. 4kPa to 399. 7kPa in the shock tube testsand the incident overpressure values were 390kPa-459kPa at the site 4. 5 meters far from the explosion center in the missile tests. The results showed that the mortality in the protection group was lower than that in the comtrol group. The severity of injury in the protection group was one or two grade less than that of the control group. The results suggested that the composite materials had a better protective effects on blast injuries in dogs.
