创伤弹道学是研究武器致伤效应和致伤机制的一门分支学科。在以往的一百多年中 ,除纵火武器外 ,枪炮是最基本的致伤武器。因此 ,创伤弹道学主要的研究内容就是枪弹和破片等投射物击中人体后在体内的运动规律、致伤效应和作用机制 ,这已成为指导火器伤救治的理论基础[1] 。一、 Traumatic ballistics is a branch discipline that studies the mechanism of lethal effects and wounding of weapons. In the past one hundred years, except arson firearms, guns and guns were the most basic weapons of injury. Therefore, the main research contents of wounding ballistics are the movement rules, the injurious effects and the mechanism of action of bullets and fragments projectiles hit the human body, which has become the theoretical basis for guiding the treatment of firearm injuries [1]. one,
