高速投射物伤是火器伤的一种主要形式。高速投射物能致伤,是因其具有动能(k inetic energy,KE),动能与枪弹质量(m)和速度(v)平方成正比:KE=1/2 mv2。由于致伤力的主要来源KE与速度的平方成正比,因此,速度在致伤力中具有十分重要的作用。有关“高速”的概念目前并不统一。英国学 High-speed projection material injury is a major form of firearm injuries. High velocity projectiles can be injured because they have k inetic energy (KE), and kinetic energy is proportional to the square of the bullet mass (m) and velocity (v): KE = 1/2 mv2. Since the main source of wounding force, KE, is proportional to the square of the velocity, velocity plays a very important role in lethality. The concept of “high speed” is not uniform at this time.
