So we know that in each case the heat is going to be the opposite of the work, but the work isn't the same in these two different ways of getting from here to here, right. So let's just see it explicitly. Here's our qA.
所以我们知道在每种情形下功,与热量相差一个负号,但从这里到这里,在这两条路径,中的功是不同的,对吧?,那么让我们明确地看一下。
One can see the amalgam of these two sets of ideas in his work.
读者可以在他们作品中看到两种思想的结合。
All right, let's calculate the work that's involved with these two processes.
这些路径都是可逆的,可逆过程指的。
In practice, most of the time we work with these two numbers, Ax and Ay.
在实际过程中,大多数时间我们就用 Ax 和 Ay 来计算
And the first law says, well heat and work are different forms of energy, and we can add them, and the path dependence of these two things is somehow cancelled in the fact that we have this internal energy.
热力学第一定律说,热和功是能量的不同表现形式,我们可以把它们加起来,它们与路径相关的部分相互抵消,我们就有了内能。
