| 摘 要： | 目的：了解爆炸冲击波在生物体内的传播特征。材料方法：采用压力测试方法，研究爆炸冲击波在肝、肺、血管及皮下组织内的传播特征，并与空气中的传播特征进行比较。结果：爆炸冲击波在不同介质中的衰减速度依次为：空气＞皮下组织＞血液；不同部位对爆炸冲击波感应的敏感度依次为：颅脑＞胸腔＞肝脏；颅脑内的应力感应方式不同于其他部位，以骨性震动传导为主要特征。结论：研究结果为体外模拟研究及为爆炸性冲击伤的诊断治疗提供了理论依据。

THE TRANSMISSION CHARACTERISTICS OF EXPLOSIVE BLAST IN BIOLOGICAL TISSUE |

| Abstract: | Objective:To investigate the transmession characteristics of explosive blast in biological tissue.Materials:The transmission characteristics of explosive blast in liver,lung,vessel and tissue under skin were studied through blast pressure detection,and compared with in air.Results:The results showed that,the decline speed of the explosive blast in different media is in order:air>skin>blood;the sensitivity of different tissue on the explosive blast is in order:brain>chest>liver.The transmission to brain mainly is by vibrating through bone,which is dif-ferent from other parts of the body.Conclusion:The results can provide the basis for simulation study in vitro,and can also provide the theoretic basis for diagnosis and treatment of the explosive blast injury. |
