Because we do try to give as much partial credit as possible in these exams, since there are a lot of places where small mistakes can result in the wrong answer.
因为我们会尽量把能给你的步骤分都给你,在对于这种考试时，因为有很多地方,只要出一点小问题就会导致最后结果出错。
-
You can run into issues of things like overflow, underflow, with floating point numbers and when you see a whole bunches of ones, it's particularly a good time to be suspicious.
来看看哪儿会出问题，你可能会碰到浮点数中的溢出和下溢问题,当你碰到一系列这种问题后，可能就会适时的开始怀疑结果的正确性。
-
So the end result, because someone wrote this function years ago is that printf takes this thing, takes this thing, David plops David inside the middle of that formatted string and then renders the whole result.
基于这是某人多年以前写的程序,最终的结果是打印出这个，这个，在格式化字符串中间的,然后返回结果。

So you cannot tell from the average everything that happened because another way to get the same 0 is to just not move at all.
所以说平均速度并不能提供所有的信息,因为完全静止所得出的结果也是0

Once that's clear, we will send it to the necessary application, be it a search engine or anti-virus software, or a stock search, or shopping, or FriendFinder - anything that can be plugged into this kind of platform.
结果一出,页面将会转到相应的应用，像，搜索引擎，或者，杀毒软件，或是，股票搜索，购物，交友网站,任何能够接入平台的东西。

Austria has given Indian observer status which means that it's not impossible to imagine a more intergrade rule of India in east Asian economy, if it moves in that direction.
奥地利还给出调查结果称,如果印度继续按照原政策发展,那么想要在东亚经济体中,将印度摆到中等国家的想法，是不可能的。

So he says, no one would take seriously the proposal that a human organism learns through experience to have arms rather than wings, or that the basic structure of particular organs results from accidental experience.
他认为,没人会相信人体组织通过学习经验,长出了手臂而不是翅膀,或者特定器官的基本结构,是偶然经验的结果

Well, it turns out that people tended to give an answer close to the number that came up on the wheel of fortune.
结果表明人们会更愿意给出,接近他们刚才转出数字的答案
-
The basic idea in solving these equations and integrating is you find one answer, so then when you take enough derivatives, the function does what it's supposed to do.
解决这类方程以及积分的基本思想就是,你求出一个解,然后进行多次求导,求导的结果就满足条件
-
When you do these calculations, which I just did for insurance-- I was talking about insurance companies-- assuming that risks are independent, everything's independent and we've got it all figured out.
当你试图去,做保险相关计算时,我指的是保险公司...,假定风险是独立的,事件都是独立的,可以算出一个结果
-
They might say my sample period was off, ... but that's what the theory-- ... using my data for the sample period that I computed-- the expected returns and co-variances says one should do.
他们可能说我的采样周期是有问题的，不过我的结果都是靠理论-,我采用自己收集的数据计算出-,预期收益和协方差可以用来指导我们的投资行为。

So, for example, here we're showing rubidium and potassium and sodium plotted where we're plotting the frequency -- that's the frequency of that light that's coming into the metal versus the kinetic energy of the electron that's ejected from the surface of the metal.
让大家看来都是可以理解的事情,就是把不同金属的观测结果,画到一张图里面来，例如这里,我们展示的是钠，钾,铷的频率-这是照射金属的光的频率,和金属表面出射电子动能的关系。
-
Well, you'll know when it crashes, that doesn't help you very much, but you can't always tell whether something's stuck in an infinite loop or whether it's simply taking a long time to compute.
好，你将学到它在什么时候会崩溃，这对你帮助并不大，但是你不能辨别出到底是在一个循环中,有什么东西卡住了呢,还是程序需要很长的时间来计算一个结果呢。
-
So you can see that we're starting to have a very complicated equation, and it turns out that it's mathematically impossible to even solve the exact Schrodinger equation as we move up to higher numbers of electrons.
所有你们可以看到我们得到了,一个非常复杂的方程，结果是它在数学上是,不可能解出确定的,薛定谔方程,当我们考虑更高的电子数目的时候。
-
It's using its set of rules to deduce the value and print them back out.
计算器用自己的规则,去计算出结果来并返回。
-
Which is, and we're going to do some examples of this, initially we just typed in expressions Python into the interpreter; that is,directly into Python And as I suggested last time, the interpreter is actually a program inside of the machine that is basically following the rules we're describing here to deduce the value and print it up.
也就是，我们将会对这一点讲解一些例子，一开始我们只是简单的把表达式输入,到解释器里面去，也就是直接传给,我上次跟大家讲过，解释器实际上是,机器内置的,按照我们描述的规则,来推算出结果值并把值显示出来的一个东西。
-
So that means that we don't have to worry about things like wave functions when we're talking about Lewis structures, but because they're so simple to use and because they so often predict the electron configuration of molecules accurately, we end up using them all the time in chemistry, so it's very valuable to know how to draw them correctly and to know how to work with them.
因此这也就意味着我们在讨论路易斯结构的时候,不需要担心波函数之类的东西，但是由于路易斯结构不仅简单易用,而且用它来预测分子的电子排布,经常可以得到非常精确的结果，结果我们在化学中一直都在用它，因此知道如何正确地画出并运用,路易斯结构是非常有价值的。
-
The highest occupied orbital is now the 2 s orbital, 1 s 2 2 s 1 so we're going to end up with boron 2 plus 1 s 2, 2 s 1, plus the electron coming out of there.
现在最高的被占据轨道是，2，s，轨道，因此结果应该是正二价的硼，再加上一个出射的电子。
-
So it turns out in C, you can absolutely represent the idea of a condition, a branch, a fork in the road.
结果在C语言中，你们完全可以表示出环境的概念,一个分支，一个三岔路口。
-
Everyone knows from calculus that if you're trying to find a function about which you know only the derivative, you can always add a constant to one person's answer without changing anything.
学过微积分的人都知道,如果你想根据已知的导数,求出其原函数,你总是可以给某人的答案,随便加一个常数,且不影响结果

And it sure enough prints what we expected it to print.
现在如果我显示下ivys的内容,它肯定会显示出我们期待的结果。
