But down below there's plenty of new energy changing the political landscape.

但在山下，有大量的新力量正在改变政治格局。

But how that energy changes depends on the system.

但是能量如何变化取决于系统。

It can't be calculated from the energy change or any other thermodynamic factor.

它不能从能量变化或任何其他热力学因素来计算。

So, when something does work on a system, its energy changes.

所以，当某些东西真正起作用时 在一个系统上，它的能量会发生变化。

Like enthalpy and entropy, we can't directly the free energy change of the whole reaction.

像焓和熵一样， 我们不能直接表示整个反应的自由能变化。

History tells us that when the dominant source of energy changes, power relations change as well.

历史告诉我们，当主要能源发生变化时，权力关系也会发生变化。

And what we have shown is that the symptoms are very likely caused by energy changes inside the brain.

我们已经证明，这些症状很可能是由大脑内部的能量变化引起的。

The standard free energy change of formation for a compound, then, is just the difference between its standard free energy and that baseline.

那么，化合物的标准自由能形成变化就是其标准自由能与基线之间的差异。

A large change in enthalpy can determine the direction of a free energy change, even if the entropy changes in the opposite direction, and vice versa.

焓的大变化可以决定自由能变化的方向，即使熵的变化方向相反， 反之亦然。

So scientists created a baseline by setting the standard free energy change of formation for an element in its most stable form at standard state to zero.

因此，科学家通过将标准状态下最稳定形式的元素的标准自由能形成变化设置为零来创建基线。

One reason is, as you can see on the mass-energy graph, light nuclei that fuse together undergo a much larger energy change than heavy nuclei that break apart.

原因之一是， 正如您在质能图上看到的那样，聚变在一起的轻核比分裂的重核经历的能量变化大得多。
