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

    这样想一下:如果旋转什么东西这个方向将会变化。

  • 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.

    比如一张纸中心旋转,看看有多困难

  • 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不是绕着地轴旋转的。

    youdao

  • 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地球绕中轴旋转作为单位时,(这种偏离)相当于一秒钟时间

    youdao

  • Its spin "axis" can point in one of two directions, thereby encoding a bit, and can flip over, thereby performing a simple computational operation.

    粒子的旋“指向两个方向之一因而记录位元资讯,借由翻转执行一个简单运算操作。

  • 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.

    如果我们个,经典比喻考虑的话经常会帮助我们建立起一些概念就是我们可以电子的,自旋想象是它绕着轴自转。

  • 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.

    旋转属于典型驱动系统,通过驱动杆的水平转动可使欠驱动杆由垂直下摆位置竖直向上位置。

    youdao

  • 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.

    仔细观测应该能发现其他有关相对论影响由于脉冲星自转周围空间—时间环境的影响造成对自转轴摆动的影响。
