在坑道内实施火炮实弹射击较在野外对人体的影响力大,根据实际观察,以耳鼓膜的损伤最为多见。这可能与坑道是半密闭的工事及发炮时所产生的爆震波有关。下面谈谈我们是怎样预防鼓膜爆震伤的。第一次坑道内实弹射击时发出炮弹九发,共有五名战士参加,因只采取了简单的预防措施,即发炮时张嘴,在发炮后发现,瞄准手的左耳及一炮手的右耳鼓膜穿孔,出血。经详细研究,方找出产生鼓膜爆震伤的主要原因是:坑道的桶壁质地坚硬,发炮时所产生的强大气压波撞击到无缓冲物质的桶壁被折回作用于鼓膜,此压力大于咽鼓管内之气压而致穿孔。
The implementation of artillery fire in the tunnel firing more than the impact on the human body in the field, according to the actual observation, the most common eardrum damage. This may be related to the fact that the tunnel is a semi-airtight fortification and the detonation wave generated when firing. Here to talk about how we prevent tympanic membrane blast injury. When the first tunnel was fired, nine artillery rounds were fired. A total of five fighters participated because only simple precautions were taken, namely when the gun was fired, it was found after firing that the left ear of a hand and the right hand of a gunner Eardrum perforation, bleeding. After a detailed study, to find out the main reason for the occurrence of tympanic membrane blast injury is: the tunnel wall texture hard, strong barometric pressure generated by the gun hit the unbuffered material barrel wall is folded back to the tympanic membrane, the pressure is greater than Eustachian tube pressure caused by perforation.
