You need a functional form that connects the value at one state of matter, the freezing point of water to another phase change, the boiling point of water.

你需要一个函数形式来,连接物质某个态对应的温度值，如水的冰点，和另一个相变,如水的沸点。

And if the test is true, it will change the value of this program counter to point to some other place in the memory, some other point in that sequence of instructions, and you'll keep processing.

如果测试结果为真，它会改变程序计数器的结果去,指向记忆存储器里的其他地方，指令序列里的其他地方，然后你会继续这个过程。

So, let's change our graph where we now have this zero point set as the two individuals hydrogen atoms, and then we see that our h 2 molecule is at the negative of the dissociation energy, or the negative what that bond strength is.

那么让我们把曲线图中的零点能改到,两个分离的氢原子处，那我们就会看到,氢分子就是负的离解能，或者负的键的强度。

OK, we're going to do this reversibly, which means we're going to slowly change the external pressure very, very slightly at a time, so that at every point we're basically in equilibrium, p2/ until the pressure reaches a new smaller pressure p2.

整个过程保持可逆，外界压强,变化得很慢，每一个瞬间,都保持平衡，直到压强减小到末态值。

The sum of path number 2 and path number 3 get me to the same place, so the energy change by going through this time path, this intermediate point here back all the way to final state should be the same the red path.

而经过路径2和3可以3,到达同样的末态，因此经过路径,2和3带来的能量的变化，与路径1带来的,能量变化相同。

Ah-ha. What does that say to do? It says, 3 gee, make min index point to there min value be 3. Change j. Is 6 bigger than 3?

啊哈，这该怎么处理呢？,让MinIndex指向那里，MinVal是,改下j值，6比3大么？

OK. What does that say? I'm going to change MinIndex min index to also point there n value is 8, j starts off here, and I say, OK, is the thing I'm looking at here smaller than that? Yes.

好的，这意味着什么？,我打算交换，让它也指向那里，MinVal是8，j从这里开始,我要找的值比这个小么？是的。
