My path in life was fundamentally altered by just a handful of courses at this place and this was in fact one of them.
在哈佛所学的一些课程,从根本上改变了我的人生道路,这门课就是其中之一。
That’s my career path, but you're in New York,
那就是我的职业规划,但是在纽约,
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 writer is the first man to map it and to name the natural objects it contains. Those berries are edible. That speckled creature that bolted across my path might be tamed. That lake between those trees will be called Lake Opal or, more artistically, Dishwater Lake.
而作者本人则是第一个为它绘制地图并为每一个自然事物,命名的人,这种讲过是可以吃的,那只身上带斑点,从我身边窜过,的动物也许能被驯服,树木之间的那个湖泊,可以叫“蛋白石湖“,或者,更艺术的,“洗盘水湖“
Path number 2 on my diagram it's a reversible, this path number 2, it's a reversible constant pressure path.
路径,首先是一个,等压过程。
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。
It configured the Mac or in this case, the Linux server to put it into my so-called path which just means I know where it is automatically.
在我的Mac机,或者是我们现在的这个Linux服务器上把它设置成,自动放到我知道的,路径下。
And I start by taking my first path here.
路径2本来。
If I look at different points in my container during that path, I'm going to have to use a different value of pressure or different value of temperature That's not an equilibrium state, and that process turns out then to be an irreversible process.
如果我要研究在路径中容器里的,不同的点,我就得在容器里不同的点上使用,不同的压强值,或不同的温度值,实际上这不是个平衡态,这个过程是,不可逆过程。
So, I could have two steps in my path.
我的路径中有两步。
I knew from the relatively limited set of course offerings that my school had the things I felt I was good at and so I went off on the path.
从相对有限的课程设置里我得知,学校里有我擅长的科目,所以我走上了这条道路。
I could have that path be very slow and steady, so that at every point along the way, my gas is an equilibrium.
我可以很慢,很稳定地经过这条路径,因此在这条路径上的任意一点,气体都处于平衡态。
I could change my external pressure through the whole process, and that's the path.
事实上外界压强,也不必固定。
Or I could have a non-adiabatic, I could take the same temperature change, by taking a flame, or a heat source and heating up my substance. So, clearly q is going to depend on the path.
也能改变温度,绝热指的是没有热传递,在非绝热条件下,也同样可以升温,比如用火或者热源加热,这样,q也应当与路径有关。
