本文提出一个与常规不同的零动量——偏置动量三轴姿态控制系统的设计方案。该系统由四个斜装的反作用轮组成。

In this paper an advanced design concept of zero-bias momentum 3-axes attitude control system consisting of four skew reaction wheels is presented.

如果你知道在你的实验装置中的原子，它们就必然具有某些动量的不确定性使得这些原子的温度高于绝对零度，不然的话，只有你的实验装置的尺度达到了整个宇宙。

If you know your atoms are inside your experiment, there must be some uncertainty in their momentum keeping them above absolute zero - unless your experiment is the size of the whole universe.

So, hopefully that kind of clears up that question. And, of course, when the velocity actually is zero, this equation that the de Broglie has put forth is valid for anything that has momentum, so if something does not have any velocity at all, it actually does not have momentum, so you can't apply that equation anyway.

能回答你的问题，当然，如果速度真的是零的话,德布罗意提出的这个方程,只对有动量的物体成立,所以如果一个东西没有速度，它没有动量，也就不能应用这个方程。
