概括

球轴承 (BB) 枪支构成重大危险,颗粒经常穿透轨道并到达内空间. 即使在更远的距离,BB也可能导致严重伤害,强调需要谨慎.

科学领域:

眼科医生眼科眼科
法医病理学法医病理学
弹道学弹道学弹道学

背景情况:

球轴承 (BB) 颗粒损伤,特别是轨道损伤,是严重的公共卫生问题.
了解BB颗粒的轨迹和透能力对于预防伤害和法医分析至关重要.

研究的目的:

为了前性地评估球轴承 (BB) 颗粒进入人类轨道和周围结构的透潜力.
在模拟撞击尸体轨道后确定BB颗粒的最终休息地点.

主要方法:

一项前性人类尸体研究,涉及四个成年头部的八个轨道.
BB颗粒从空气步枪中在不同距离 (10厘米至5米) 和位置 (骨,眼皮,轨道区域) 射出.
计算机断层扫描 (CT) 用于可视化和分类BB颗粒的最终位置.

主要成果:

在40颗BB颗粒中,37颗穿透软组织,并在CT上可视化.
大多数穿透颗粒 (51%) 最终落入内空间,46%落入周围的轨道结构.
颗粒轨迹和最终位置与排放距离有显著的相关性,较长的距离增加了内透风险.

结论:

当 BB 枪准轨道时,它们是危险的和潜在的致命的.
轨道作为BB颗粒的脆弱入口点,允许透到内和周围轨道空间,尽管有保护性.
这些发现强调了对使用BB枪的安全预防措施和意识的关键需求,特别是关于头部和轨道损伤.

Free-falling Bodies: Introduction

Free-falling Bodies: Introduction

All objects, neglecting air resistance, fall with the same acceleration towards the Earth's center due to the force exerted by the Earth's gravity. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavier ones. People believed that a heavier object had a greater acceleration when falling until Galileo Galilei (1564–1642) proved otherwise. We now know this is not the case.
