But a real key in looking at these plots is where we, in fact, did go through zero and have this zero probability density.
是我们经历这些零值,而且有这些零概率密度,我们把它叫做节点。

Physicians over the years of having this instrument have learned how to be very sophisticated about looking at these pictures and diagnosing when something is wrong inside the chest, for example.
这些年来,使用这类设备的医生,已经熟练地掌握了,通过看这些X光片,来诊断,胸部疾病的方法

So what I want to point out when you're kind of looking at these numbers here, what the significance is, look at that huge difference between what the ionization energies are for what we call those valence electrons, -- those outer shell electrons, those are core electrons there.
我在这里想要指出的是,当大家在看这些数字的时候，最重要的是，要看到这些,巨大的差异,看到所谓价电子，即外层电子的电离能与，1，s，轨道，电离能之间的巨大差异。
-
But you notice up here how close these levels are, so we are looking at very, very fine distinctions.
你能看到这些层有多接近，所以我们是在观察非常非常细微的差别。
-
And so if one is looking to keep protein at a certain level, then these sort of foods would get favored.
但还不是全部 而如果要使体内蛋白维持在某种水平上,那这些食物会比较受青睐
-
And I want to talk briefly about each of these three parts of language before looking at some other issues.
在探讨一些其他问题之前,我想简单的讲一下语言的这三个成分
-
And I'll also remind you, and we're going to see this in the next example, we talked about looking at the worst case behavior. In these cases there's no best case worst case, it's just doing one computation.
我还要提醒大家的就是，我们也会在下一个例子里发现者一点，我们谈到了要去考虑最坏的情况,在下面这些例子里,没有好情况坏情况之分，就只是一次运算。
-
Sometimes when correspondence is saved you run into these kinds of problems, so we have to guess a little bit at what she was looking at.
有时即使资料的确存在,可找不到麻烦就来了，因而，我只能去猜测她的大意了。
-
but you can sort of tell that the particle is moving slowly or rapidly by looking at the space in between these tick marks.
但你可以通过观察计时点之间的距离,来判断该物体运动的快慢
-
I am looking over here at these tables and these computers.
我从这儿去看那些桌子和电脑。
-
And even though the syntax, the characters you are about to see on the screen and in programs today onward is a little more arcane, it's a little uglier looking, you've got semicolons and parentheses and fairly arcane syntax, realize that at the end of the day these are just arbitrary human conventions, the ideas are identical to this thing here.
可能你在屏幕上，编程中见识到的,语法，字符看起来非常晦涩难懂,甚至可以说是丑陋，像什么分号啊,括号啊等等，还有一些难七八糟的语法，但是到了最后，你会发现,这些都不过是一些人为约定而已，而蕴含在里面的编程思想跟这个例子并无二致。
-
So Player I's payoff, if she chooses top and Player II chooses center, we read by looking at the top row and the center column, and Player I's payoff is the first of these payoffs, so it's 11.
参与人I的收益,如果她选上,参与人II选中,我们来看一下上行和中列,参与人I对应第一个收益即11
-
So, for example, if we were looking at the actual wave function, we would say that these parts here have a positive amplitude, and in here we have a negative amplitude.
我们看，一个波函数,我们说，它这部分幅值，为正,这部分幅值为负，当我们看。
-
Versus looking at, for example, helium or neon or argon, these are all inert gases, inert meaning essentially do not react, those were grouped together in the periodic table.
相反，他发现氦，氖，氩，都是惰性气体，惰性的意思是基本不参与化学反应，因此把它们放在周期表中的同一类里。
-
So again, looking at the shapes, now we're just combining two, we've got these two equal hybrid orbitals plus these 2 p orbitals here.
同样，我们看它的形状，现在我们仅仅结合两个轨道，我们得到这两个杂化轨道,和两个p轨道。
-
So, for example, when people, and we'll talk about this next class, were looking at different characteristics spectra of different atoms, what they were seeing is that it appeared to be these very discreet lines that were allowed or not allowed for the different atoms to emit, but they had no way to explain this using classical physics.
举个例子，当大家看到,不同原子的特征光谱时,他们看到的是一些分离的线,那可以使不同的原子,发射或不发射出去，但是这些无法用经典物理来解释。
-
So what we can say is look at each of these separately, so if we start with looking at the 2 p z orbital, the highest probability of finding an electron in the 2 p z orbital, is going to be along this z-axis.
我们可以来分别看看这些图，首先来看看2pz轨道，在2pz轨道里,找到电子的最大概率，是沿着ｚ轴。
