To counter these effects on a long-duration mission, say, Mars, astronauts will certainly need to create their own artificial gravity.

比如在火星上，为了在长期任务中对抗这些影响，宇航员肯定需要人为制造重力。

A defining feature of life in outer space (sans artificial gravity, of course).

用来描述生命在外太空的特性。

A spinning centrifuge provides artificial gravity for the astronauts who man the ship.

宇航员们需要一台不停转动的巨大离心分离机给他们的控制舱提供人造重力。

A spinning centrifuge37 provides artificial gravity for the astronauts who man the ship.

一台不停旋转的离心机为操控飞船的宇航员提供人工重力。

To test whether artificial gravity can counteract such muscle wasting, researchers subjected 15 healthy men to a zero-gravity simulation.

为了测验人造重力是否能抵消肌肉流失，研究人员对15名健康男子进行了零重力模拟。
