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。
-
It's not going to be zero this time because we have non zero heat exchange between the system and the environment, right.?
热力学量，但是现在让我们看一下,我们的特殊函数，这次它不会是零,因为系统与外界的热量交换并不是零，对吧？

u=0 And it's approximately equal to zero for all real gas processes.
在所有理想气体绝热过程中Δ,对真实气体近似为零。
-
A corporation is an entity that could be sued or could lose more money than it's worth, but the value of a corporation can never fall below zero to the investors because the investors are not liable for the mistakes of the corporation.
