ballistics 弹道学

internal ballistics 内弹道学

the science of projectile motion within the rifle 步枪内弹道科学知识。 external ballistics 外弹道学

the science of the bullet in flight 子弹飞行科学知识。 terminal ballistics

终点弹道学《包含创伤学科》

the science of the motion and action of the bullet from the instant of initial impact until it stops. 子弹的运动从发射瞬间开始到结束科学知识。

internal ballistics 内弹道学

everything that happens within the rifle from the instance the primer is ignited until the bullet leaves the muzzle of the barrel is important in terms of repeatablity;

枪射击过程中的内弹道循环包括击发到弹丸射出枪膛所经历的全部过程，击发是内弹道循环的开始。

some components of internal ballistics 内弹道的构成部分 primer 枪弹底火 powder 火药 pressure 压力 cartridge 弹药筒

barrel rifling and vibration 线膛枪管以及其震动 recoil 后坐力 bullet 弹丸

action,chamber dimensions 动作，枪膛容积

and other mechanical properties 以及其他的机械性能。

terminal ballistics

终点弹道学《创伤弹道学科》

the science of terminal ballistics involves everything that happens from the moment the bullet impacts the target until it comes to a stop ,when the target is living tissue, terminal ballistics is also referred as wound ballistics 终点弹道学科是研究枪炮弹，火箭弹以及导弹战斗部分对目标作用效应的一门学科，弹药设计和目标防护设计的理论基础。这里研究的是枪弹出膛到停止，目标为有生目标。

external ballistics 外弹道学

once the bullet leaves the muzzle until the time it hits the target.its path is influenced by two external forces-gravity and the flow of air around the bullet a solid understanding of external ballistics is imperative for long range shooting 子弹脱离枪膛口到达击中目标，受到了重力和空气动力以及推力的影响，这个会在远程狙击范畴内体现明显。

重力是一个永恒的力，它会给这个物体下坠带来每秒32英尺的加速度。

line of departure 发射线

if there were mo gravitation pull on the bullet it would travel in straight line this can be called the line of departure

如果不受地球引力，子弹在直线中飞行，这就叫发射线。

译者补充内容：发射瞬间枪管火身口轴线的延长线。
