Its rotational axis is flipped upside-down, which means that the planet spins backwards.

它的旋转轴是颠倒的，这意味着行星会反向自转。

The gravitational effect of the Moon keeps the degree of tilt on the Earth's rotational axis constant.

月球的引力使得地球的自转轴倾斜保持在一定的角度。

We can also help a pitcher get better by giving them details like the rotational axis of the pitch.

我们还可以通过向投球手提供有关球场旋转轴等的细节信息，帮助他们表现得更好。

If the Moon hadn't been there, Earth's rotational axis would have oscillated, causing rapid changes in the climate.

如果月球没有在那里，地球的转轴就会振荡，导致气候的迅速变化。

The moons of Mars, Phobos and Deimos, are so small that they play no stabilising role on the rotational axis.

火星、火卫一和火卫二的卫星都太小了，它们在转轴上起不到稳定作用。

Described another way, polar motion is when the position of the planet's rotational axis moves in relation to Earth's crust.

另一种说法是，极移是指行星的旋转轴位置相对于地壳运动。

All a planet needs to have them is a tilted rotational axis and an orbit.

一颗行星所需要的只是一个倾斜的旋转轴和一个轨道。

Surprisingly, this bot can accurately reproduce the rapid escape maneuvers of fruit flies even with no explicit control of all its rotational axes.

令人惊讶的是，即使没有明确控制其所有旋转轴，该机器人也能准确地重现果蝇的快速逃生动作。

To do that, a powerful rotational force is exerted on the test tube, causing heavier substances with higher density, like blood cells, to move away from the rotational axis.

为此， 在试管上施加强大的旋转力，导致密度较高的较重物质（如血细胞）远离旋转轴。
