摘要
实验动物为体重15.2～42.4kg的绵羊和山羊共46只。用TNT化爆和BST-Ⅰ型激波管致伤,伤后6小时进行形态学检查,以确定重复冲击的效应。结果表明多次重复冲击可使损伤显示累加效应,表现为损伤的发生率和程度增加,损伤阈值降低。
Forty-six adult sheep and goats weighing 15.2-42.2 kg were used for this study. Using the TNT chemical explosion and BST-1 shock tube. the animals were inflicted to determine the effects of repeated blasts. Morphological examinations were carried out 6h after injury. The results showed that the repeated blasts resulted in superimposed effects and revealed the increase of incidence and severity of injury, the reduction of the threshold value of the overpressure inflicting internal organs.
