"The international community has offered the North a path to get back in the good graces of the international community,".
VOA: standard.2009.04.15
The amount of work you've put in to get here depends on the path. It's not a function of state.
这些量就能,决定系统的状态了。
The reason for inexact doesn't mean it's a crummy measurement, t means that it's path dependent, and so the value of this integral depends on how you get from one to two.
这是因为它是,与积分路径有关的,因此这里的积分值,取决于从一端到二端的,具体路径。
So I could get to that object either through this path or through that path, it didn't matter which path I use to modify it, I would see it when I looked at the other. Yes.
另外一条绑定获得这个对象,无论我通过哪个绑定来修改它,我都能在两个绑定中都看到做的改变,是这样的。
PROFESSOR: Okay, so before we get to some of these course policies, I think I'll tell you a little bit about my path to chemistry as well.
教授:好,在我们讲这门课的相关政策之前,我也先和你们说说我怎么走上化学的道路的。
The biggest thing for me on that path is I needed to draw something out and I needed to get it out of my head.
在我看来,这条路上最重要的莫过于,是需要描绘出一些东西,再把它们忘却。
So again, for both heat and work we don't get the same result. Now let's look at our special function, right. So here's path A.
所以,再一次说明,对于热量和功,我们得到的结果是不同的,现在让我们看看我们的特殊函数。
Define the path. Get all of these really clear, and you've basically solved the problem.
把所有这些搞清楚,你就基本上解决这个问题了。
This depends on the path. It tells you right here the path is constant pressure. These don't depend on the path, right. V doesn't care how you v get there. u doesn't care how you get there.
这由变化的具体路径决定,这个小脚标表明过程是恒压的,这些量都与具体路径无关,即不管是通过什么路径使得体积变化为Δ
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。
