So we don't have to keep the speed constant.

不用保持速度恒定。

The final value that motion can take is linear, which keeps animation speed constant.

最后，motion 属性还可以带的一个值是 linear，该属性让动画以恒速变化。

And the relationship that he put forth is that the momentum is equal to Planck's constant times nu divided by the speed of light, or it's often more useful for us to think about it in terms of wavelength.

爱因斯坦提出的关系式是,动量等于普朗克常数,乘以υ除以光速，或者用波长来表示,通常更容易让我们想明白。
