We're not going to have the constant pressure heat capacity, but the constant volume heat capacity.
我们将不会具有恒定的压力热容量，而是具有恒定的体积热容量。
The first is the heat capacity of the materials that constitute the city, which is typically dominated by concrete and asphalt.
首先是构成城市的材料的热容，通常由混凝土和沥青主导。
In the countryside materials have a significantly lower heat capacity because a vegetative blanket prevents heat from easily flowing into and out of the ground.
在农村，材料的热容量要低得多，因为植被可以防止热量轻易地从地面流入或流出。
So your heat capacity is zero.
所以你的热容是零。
So the heat capacity is zero again.
所以热容又是零。
And the heat capacity is a constant.
热容是常数。
Which means the heat capacity is zero.
那意味着热容为零。
So now we can look at the heat capacity.
那么现在让我们来看看热容。
So why should the heat capacity be zero?
那么为什么热容要为零？
And that means the heat capacity is zero.
那意味着热容等于零。
What's the heat capacity at high temperature?
高温时的热容是什么？
Today we're going to talk about heat capacity.
今天我们将要讨论热容的概念。
So we've seen the heat capacity limiting cases.
那么我们已经看到热容的极限情况。
Because I do want to look at the heat capacity.
因为我想来看看热容。
So that's the vibrational heat capacity of a solid.
那么那就是固体的振动热容。
Well, what you find out is the heat capacity is zero.
好，你们发现热容是零。
So we've seen the limiting cases for the heat capacity.
我们已经看到极限情况下的热容。
What was the low temperature limit of the heat capacity?
热容的低温极限是什么？
But I want to talk a little bit about the heat capacity.
但我想谈论一点儿热容。
Why did the heat capacity go to zero at low temperature?
为什么热容在低温时是零？
Now, this looks kind of complicated for the heat capacity.
现在，这个热容看起来有一点复杂。
kT The heat capacity is du/dT. It's zero because, here's kT.
热容是du/dT，它等于零是，因为这是。
So in that case, the high temperature limiting heat capacity is zero.
所以在这种情况下，高温极限的热容是零。
Of course it's really the same result for the energy and the heat capacity.
当然对于能量，和热容的确是同样的结果。
OK. Given that, then I want to talk a little bit further about the heat capacity.
好，在这样的假定之下，然后我想谈论更多的一点，关于热容的问题。
Basically, in that case, the heat capacity Nk it's not just Nk for one vibrational mode.
本质上在这种情况下，热容，对一种振动模式不只是。
You can learn a tremendous amount about that by making measurements of the heat capacity.
你们能了解关于这些的极多的内容,通过测量热容。
What's the heat capacity at high temperature, if there's a finite number of states available?
如果有有限数目的可能的状态，高温时的热容是什么？
So you get the zero limiting value for the heat capacity, and the energy itself is also zero.
所以热容的极限值是零，能量本身也是零。
And in particular, I want to talk about both the heat capacity and the energy that we've seen.
特别地，我想谈谈热容，和我们已经看到的能量。
