rifled
Học thuậtThân thiện
Definition
Adjective: 1. Of a firearm's barrel: Having a series of spiral grooves (rifling) cut into the interior surface. These grooves cause a projectile to spin, stabilizing its flight for greater accuracy. * The museum displayed a collection of antique rifled muskets from the 19th century. * Modern handguns and sniper rifles have rifled barrels.
Usage Notes
- The term rifled is used almost exclusively to describe the barrel of a firearm or artillery piece. It is the opposite of smoothbore.
- It is a technical, descriptive adjective. You would not typically use it to describe the act of firing the weapon (e.g., "He rifled the gun" is incorrect).
Advanced Usage
- The concept can be extended metaphorically to describe other cylindrical objects engineered with spiral grooves for a specific purpose, though this is rare.
- The engineer designed a rifled tube to impart a spin to the fluid, improving mixing efficiency. (Technical/engineering context)
