The team built a 38 foot tall centrifuge that rotated at 3 miles per hour to imitate artificial gravity.

该团队建造了一个 38 英尺高的离心机，以每小时 3 英里的速度旋转，从而模拟人工重力。

The O'Neill Cylinder, as it is known today, creates artificial gravity by rotating on its axis.

众所周知，奥尼尔圆柱体通过绕其轴旋转产生人造重力。

The astronauts compared the growth and shape of cells in artificial gravity and zero gravity, so as to study their changing rules and mechanisms.

航天员们比较了人工重力和零重力环境下细胞的生长和形状，研究了细胞的变化规律和机制。

Until we develop artificial gravity in a space ship or on another planet, we should assume that astronauts will spend time living in microgravity.

在我们在太空船或另一个星球上开发出人造重力之前，我们应该假设宇航员将在微重力中度过一段时间。

Any habitat must have replenishable sources of  food, water, breathable air, and medical supplies; and it must spin to produce artificial gravity, though scientists are unsure how much gravity we need.

任何栖息地都必须有可补充的食物、水、可呼吸空气和医疗用品来源；它必须旋转才能产生人造重力， 尽管科学家们不确定我们需要多少重力。
