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。

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。

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.

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。
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。
Still, one might imagine that the particle's spin around any axis was set before anyone ever came along to prod it. That's certainly what we ordinarily assume in life.
不过，我们可能会设想，粒子沿所有轴的自旋是在测量前就确定了的，这正是一般我们在生活中所做的假设。
For the sake of his life, Galileo recanted his views in 1633, admitting that the earth did not spin on its own axis.
为了保住性命，1633年，伽利略被迫宣布放弃日心说，承认地球并不是绕着地轴旋转的。
You can spin the board around many different axis, and even combine several rotations in to one trick.
你可以在不同的旋转轴的董事会，甚至数轮合并到一个把戏。
Magnetic axis to ensure there is enough pressure to maintain its solid connection so that you can divide the next spin.
可以保证电磁轴有足够的压力，保持其连接稳固，这样就可以旋下隔膜。
Its spin "axis" can point in one of two directions, thereby encoding a bit, and can flip over, thereby performing a simple computational operation.
粒子的自旋“轴”会指向两个方向之一，因而记录一个位元资讯，也可借由翻转而执行一个简单的运算操作。
Fluctuation axis adopt high precision screws spin umbrella gear rotating.
上下轴采用高精度螺丝旋伞齿转动。
One way to think about it, if we want to use a classical analogy, which often helps to give us an idea of what's going on, is the spin of an electron, we can picture it rotating on its own axis.
如果我们用一个，经典的比喻来考虑它的话，这经常会帮助我们建立起一些概念，就是我们可以把电子的，自旋想象是它绕着轴自转。
Such nuclei spin on an axis like miniature tops, giving rise to a magnetic moment, which means the nuclei act as if they were bar magnets with a north and south pole.
这种原子核像缩微的陀螺围绕一根轴线自旋，产生磁性，像具有S极和N极的磁铁棒一样。
The rotating pendulum is a typical underactuated system with a rotating shaft of the motor attached to the end which is free to spin about an axis parallel to the axis of rotation of the pendulum.
旋转摆属于典型的欠驱动系统，通过驱动杆的水平转动可使欠驱动杆由垂直下摆位置转到竖直向上位置。
Careful observations should also detect other relativistic effects, including the precession of the pulsar's own rotational axis due to the effect of the pulsar's spin on the surrounding space-time.
仔细的观测还应该能发现其他有关相对论的影响，如由于脉冲星自转对周围空间—时间环境的影响而造成的对自转轴摆动的影响。
