1·Moreover, the shaft is deviated from the spin axis.

此外，该轴偏离旋转轴线。

2·A simple proof of six invariants under the transformation of spin axis is put forward.

给出了二次曲面在转轴变换下的六个不变量的简易证明。

3·Since that pulls mass closer to the planet's spin axis, it causes the planet to rotate faster - just as an ice skater spins faster when she pulls her arms towards her body.

由于质量朝地球旋转轴靠拢，这就导致地球旋转速度加快- - -就像一个速度滑冰选手，当她把胳膊向身体收拢时就会旋转得更快。

4·The shaft is structured to optionally move in the offset cam, and the display panel unit is structured to rotating around a spin axis when the shaft moves in the offset cam.

该 轴构造成在偏心凸轮内选择性地移动，并且显示面板单元构造成当轴 在偏心凸轮内移动时绕旋转轴线旋转。

5·Imagine it like this: If you spin something, the direction of the axis tends to wobble.

这样想一下：如果你旋转什么东西，这个轴的方向将会变化。

6·So you can see, if it's spinning on its own axis in this direction we'd call it spin up, where as this way it would be what we call spin down.

你们可以看到，如果它绕自己的轴朝这个方向转，我们就说它是自旋朝上，这个方向我们叫它自旋朝下。

7·The women are at their most physically expressive in this private world, but then life and death come calling and spin that world right off its axis.

女人们在这个隐秘的世界里展示着她们最生理的东西，然后死亡降临，把这个世界又转出了它的轴。

8·Since Earth’s rotation rate varies, so would the value of one second when it’s defined as a fraction of the time it takes for one spin of the Earth on its axis.

由于地球自转速率发生偏离，因此当把地球绕中轴旋转一圈作为一个单位时，（这种偏离）就相当于一秒钟时间。

9·Then you would try to measure how hard it is to spin your object around that axis.

然后去测量,绕该轴旋转物体的困难程度。

10·For example, you can try to measure how hard it is to spin this sheet of paper about an axis that is in the center of it.

比如，试着让一张纸绕其中心轴旋转，看看有多困难。
