This is a point that is often confusing, because you can think, well maybe I could calculate what the internal pressure is even for this very rapid process.
这一点可能让你们很困惑,因为你们可以想象这个过程,我也可以计算在这快速的变化中,内部压强是多大。
The idea of risk, that economic risks can be pooled, is an intuitive one that has occurred to people throughout history.
风险理论,即认为经济风险可以分摊,是历史过程中,人们逐渐发现的理论。
It's a process of undoing and undermining that really eats away at the argument, we could argue, throughout the entirety of Areopagitica.
这是个论点开始慢慢被侵蚀破坏的过程,我们可以争论这点,贯穿整个《论出版自由》中。
But you actually need to keep a few caveats in mind as you do this, which is the fact that trends predict a lot of chemical properties, but they can't predict everything in terms of biological properties.
不过在你使用的过程中,需要牢记一些注意事项,那就是元素周期律可以预言很多化学性质,但是不能预言一切性质,比如生物学性质。
And inside of the machine, and things we'll talk about, there is a process that will allow that sequence to be executed as described in that recipe, so it can behave like any thing that I can describe in one of those recipes.
在机器里面,还有我们要说的,里面有一个我们允许的,在方法中描述的,将要被执行的序列的过程,因此它可以像我在方法之中,描述的任意一种那样来表现。
We talked about the path last time being very important. Defining the path.
我可以在整个过程中,改变外界的压强。
One of the inputs to the problems we're gonna be working on this semester and if you continue on in this world how much thought it takes to implement something, how much time it takes to run something, how much space it takes to run something?
我们将在本学期集中探讨这些问题,或者在课程之后你们也可以继续研究,为实现一些功能要有多少想法,在运行过程中又将花费多长时间,需要多大的空间?
That's something you can be telling me about as you get through the course.
你们在学这门课的过程中,都可以和我分享的收获。
From that standpoint, from that theoretical standpoint, comes a methodological approach which is, if they're all the same then you could study human learning by studying nonhuman animals.
从这个理论观点中,可以得出一种研究方法,即,如果人类与动物并无差别,那你就能通过研究非人类动物的学习过程,来研究人类的学习过程。
This conversion from a mechanical energy into a chemical energy can be nicely visualized when one fills a hair cell with a sensitive die that responds to the calcium ions that influx into the cell.
如果在毛细胞中注入,对钙离子敏感的物质,可以精确地模拟,这一机械能到化学能的转化过程。
We talked about modern imaging methods and this is an example of an fMRI, a functional MRI; a map of the brain that not only shows you the anatomy of the brain but shows you something about the chemistry of what's going on inside.
我们还说到现代影像技术,这里是一幅脑部功能性磁共振成像图像,一种功能性的磁共振,图中不仅可以看到脑部解剖学图像,也可以看到一些脑内的生化过程
All right. What does this have to do with my divisor example? This says I can make tuples, but imagine now going back to my divisor example and I want to gather up the elements as I go along. I ought to be able to do that by in fact just adding the pieces in.
这意味着我可以创建元组了,但是想像下回到我们的除数的例子,在处理过程中我们想把目标数的除数,收集起来,我应该能够通过把这些数,一个一个加进来来实现这个目的,我正是要去这么做,也就是。
So the satisfactions of the moment are for Milton deferred here; and it's something like a recognizable process of deferral and postponement that you will see beginning to form themselves at the very center of Milton's poetic imagination.
因此对这一时刻的满意就是因为弥尔顿把它推迟到这;,而且就像一个可以察觉的推迟过程,从一开始你就会看到这些推迟是顺其自然的,这在弥尔顿的诗歌想象中可以看到。
But in terms of drugs that don't look like maybe this compound was used in the synthesis, many of them might have used thionyl chloride, because it generates such a nice reactive intermediate that you can go on and make a bunch of different compounds from that intermediate.
但是对于药物来说,它们可能跟合成过程中用到的这种化合物并不相像,很多药物的制造过程中都会用到亚硫酰氯,因为它能产生活性如此之高的反应中间体,以至于你可以继续利用反应中间体,来制造一堆不同类型的化合物。
I don't find that my analysis is profound in the final answer, I just took some estimates using my data and, again, we could-- if someone wanted to argue with us they could argue with my estimates of the expected returns of the standard deviations and the covariances, but not with this theory.
我在计算过程中并没有做太深入的分析,我只是用我的数据做了一下大概的估计,我再说一次,我们可以-,如果有人想就这个问题与我们争辩,他们可以争论我对期望收益的估计,或是争论标准差和协方差的估计值,但并不会针对理论本身。
As you can tell from the cameras, the course is in fact filmed for reasons of distance education and your benefit for review; we've been working on this past summer what we dubbed cs50.tv which is our own delivery mechanism for these videos.
你们从大屏幕上可以看出来,该课程实际上是为远程教育拍摄的,你们能够在评论的过程中获益良多,今年夏天我们一直忙于cs50。tv网站的事,这样,拍摄完的视频就可以上传到这个网站。
These won't be graded, you don't have to turn them in, it's just to give you some extra practice if you want while you're studying for the exam.
这些题目不会记分,你们也不需要交上来,只是如果你需要的话,这可以让你,在准备考试的过程中得到更多的训练。
Alan Turing In 1936, that same guy, Alan Turing, showed that with six simple primitives, anything that could be described in a mechanical process, it's actually algorithmically, could be programmed just using those six primitives.
在1936年,还是那个人,展示了六个基本类型,可以在计算过程中,表达出任何含义来,其实这是演算性质的,可以根据六个数字编程。
There's no change in them, and then we also looked at some at non-state functions, work and heat, and saw that those aren't zero going around a cycle. Of course you can do work in a cyclic process, and heat can be exchanged with the environment at the same time.
它们不会有变化,然后我们研究了,一些非态函数,功和热量,并看到,沿着循环行进一周的话,它们并不是零,当然你可以在,一个循环过程中做功,而同时热量可以在系统,与外界环境之间进行交换。
