You just change volume to pressure and basically you're looking at enthalpy under a constant -- anything that's done at a constant volume path with energy, there's the same thing happening under constant pressure path for enthalpy.

可以看到这就是把体积换成了压强,一般我们都是在一种恒定状态下,考虑焓的，任何在恒容条件下,能伴随能量变化的东西，也在恒压条件下伴随焓同样地变化,所以你可以经常。

And indeed, as we shall see, well, the tragic view of life, which the Greeks invent and which characterizes their culture, is there right at the beginning in the Iliad and the Odyssey.

确实,我们可以看到,悲剧人生观,在伊利亚特和奥德赛的一开始就有所体现,这是希腊人首先提出的,体现了他们的文化性格

So if we go to the ground state, what you see is we're at that lowest energy level, and we only have one possibility for an orbital, because when n equals 1, that's all we can do.

如果我们在基态上，你可以看到，我们在能量最低的态上，只有一种，可能的轨道，因为n等于1，只有这种可能。
