Gliding joints are usually small, and always flexible so that bones can slip and slide against each other.

滑动关节通常小，而且也，以便骨骼可以相互滑动。

All these motions use gliding, or plane joints, like the one between the distal ends of your radius and ulna, and the carpal bones of your wrist.

所有这些运动都用滑动或平面关节，比如桡骨远端和尺骨之间的关节，还有手的骨。

The scientists 3D-printed models of the various joints and found that a claw with a cocking slip joint can snap closed with enough force to generate shockwaves.

科学家们用 3D 打印了各种关节的模型，发现带有翘起滑动关节的爪子可以用足够的力快速闭合以产生冲击波。
