However, most of its internal heat comes from the action of its muscles.

然而，它的大部分内热来自肌肉活动。

Earth's internal heat, fueled by radioactivity, provides the energy for plate tectonics and continental drift, mountain building, and earthquakes.

地球内部因放射而产生的热量为板块运动、大陆漂移、造山运动和地震提供了能量。

It is simply power derived from the Earth's internal heat.

它真正的能量来自地球内部的热力。

We have discovered that this partial derivative that appears in the definition, the abstract definition of the differential for internal energy, is just equal to the constant volume heat capacity.

我们还发现,这个偏微分出现在了，内能的偏微分,定义式中，它也就是热容。

And because there is an explicit relationship between u, delta u, q and w, you can always find the easy way to derive the change in internal energy or the heat or the work.

因为Δu，q和w之间,有明确的关系，一般来说,内能或热或功的变化,易于计算。
