1·There is a third movement the hypothesis covers called precession.
这个假说所包括的第三种运动叫做岁差。
2·Precession, basically is the change in the direction of earth's axis of rotation.
岁差,基本上是地球自转轴方向的改变。
3·The Earth's axis in its orbit does the same thing because of a phenomenon called precession, and is now facing a different star than it did 5, 000 years ago.
地球的地轴做了类似的事情,因为一种现象叫做岁差,现在所面对的是与5000年前不同的星星。
4·It is due to a phenomenon called the precession of the equinoxes.
这是由于岁差现象所导致。
5·The moment of precession and nutation is a prerequisite to explain these phenomena and one main way of building nutational serial of rigid Earth.
岁差章动力矩是解释这些现象的前提条件,也是建立刚体地球章动序列的最主要方法之一。
1·That's key to detecting precession, because during each eclipse astronomers can determine the precise angle of the radio signal and therefore the pulsar's wobble over time.
这是探测进动的关键,因为在每次遮挡期间天文学家们可以确定放射线信号的精确角度,并因此断定脉冲星的抖动时间。
2·The theory of relativity also includes some more esoteric details, one of which is called spin precession.
相对论还包括一些更加深奥的细节,其中的一个被称作自转进动。
3·This gyroscopic motion is called precession.
此陀螺运动叫做进动。
4·It sets forth the computing method of rotor moment of inertia of the propeller and engine as well as the computing method of additional moment or angular velocity produced by precession.
阐述了螺旋桨和发动机转子转动惯量的计算方法,由进动产生的附加力矩或角速度的计算方法。
5·This phenomenon is called "precession".
这个现象被称作“进动”。
1·First of all, if you increase the torque, the upstairs, then it says that the precession frequency will increase.
首先,如果力变大了,上面,说旋进的频率,也会上升。
2·And now you will see an instantaneous increase in the precession frequency.
你们能看到旋进频率的,瞬间上升。
