"President Obama has made it clear that the United States will not be defined simply by what we are against, but by what we are for the opportunity,liberties, prosperity and common aspirations we share with the rest of the world,"

Well the fact is it could be hundreds of foods in the American food supply, and what's noteworthy about this particular list of ingredients, is that it's fifty-six entries long; fifty-six things in this particular food and we defined it as food.

实际上,答案可以是,几百种美国食品,值得注意的是,这张配料单,居然包含了五十六种配料,这种由五十六种物质构成的东西,而我们还将它定义为食品

If we defined food differently: that it's something that nurtures the body, something found in nature, something that doesn't harm the environment-- there are a number of criteria one can apply to define a food-- then we might come up with a different definition than this, but this is the way the nutrition field generally looks at it.

如果我们给出不同的定义,滋养身体的物质,在自然界找到的物质,不会威胁到身体的物质,有很多标准可以拿出来定义食物,我们也许可以就此重新进行定义,但这就是营养学看待食物的方式

What we've done is refocused. We are refocused on 'why are we there?' And we've rearticulated our core objectives and our core interests in a more defined strategy for how do we actually turn the tide and begin to make progress.

We defined an accredited investor as someone who can participate in a DPP or other sophisticated programs.

我们把可信投资者定义为,有资格加入DPP或者其他复杂项目的人

But we've defined the enthalpy of those elements in their stable state at room temperature and pressure as zero, right?

但我们已经定义了这些,元素处于它们室温和常压下,最稳定的状态时的焓为零，对吧？

But remember that we need to multiply it by the volume here, the volume of some sphere we've defined.

但记住我们需要把它乘以体积，乘以一个我们定义的壳层的体积。

I think you may have defined it already, but I couldn't find a definition of strictly in the book we have.

我想你之前已经定义过了,但是我在课本里没有找到,“严格”的定义

I think of data hiding as basically saying, one can only access instance values, or, we'll call them that, instance values through defined methods.

一个人仅仅可以访问实例变量，或者，我们可以这么来说，通过定义好的方法，来访问实例的变量。

You cannot say to me, "Take a force, due to a spring, and see what force it applies and divide by the acceleration and get the mass, " because we haven't defined force, either.

你不能说,"给弹簧施加一个力,看看它能提供多大的力,然后除以加速度,得到质量",因为我们还没给力下一个定义

float So thus far, when we've defined -- declared an int and a float, 2 and so forth, we just put one value in there, the number 2, the number 3.14, just one single value.

至此，当我们定义--声明一个int，和一个，等等，我们只要在那里放置一个值，数字，数字3，14，只有一个值。

I want to point out that the zero energy is defined as when you have a naked proton -- where the electron has popped out -- that's what we've defined as zero energy up to this point when we're talking about single atoms.

我想指出，这里零点能的定义,是当我们只有一个裸露的质子,而没有电子时-,到目前为止对零点能一直采用这样的定义,当我们在讨论单个原子时。

Alright. So, since we have these terms defined, we know the frequency and the wavelength, it turns out we can also think about the speed of the wave, and specifically of a light wave, and speed and is just equal to the distance that's traveled divided by the time the elapsed.

好了，我们已经定义了，这些术语，我们知道了，频率和波长，现在可以来考虑,波的速度了，特别是光波的速度，速度等于它走过的距离,除以所用的时间，因为我们。

All right, so let's just see what we got, we'll print univs. Nope, not defined.

我们来显示下univs数组，噢，还没定义。

The reason in our radial probability distributions we start -- the reason, if you look at the zero point on the radius that we start at zero is because we're multiplying the probability density by some volume, and when we're not anywhere 0 from the nucleus, that volume is defined as zero.

在径向概率密度里，我们开始,如果你们看半径的零点，我们从零点开始,因为我们用概率密,度乘以体积,而当我们，在离核子很近的地方,体积是，所以我们会在这里。

Indeed, swap in your printout there is just defined as now taking *a and *b and then it also uses the * later, but we'll come back to what the different uses of the * means, but for now I claim conceptually it just means swap has access to the locations of its parameters.

的确，在打印资料中的swap被定义为,携带*a和*b，之后它也是带*号的，但是我们将说明*的不同用法，现在，我断言swap可以,使用参数的地址。

So, let's, for example, look at nitrogen. So n 2, we can do the chart here in green, so it's the green dotted line, and what we see is that we have now defined this energy as where the 2 nitrogen atoms are separated.

那么，让我们举个例子，看一下氮，那么氮分子，我们可以把它用绿色曲线画在这，这是绿色的虚线，可以看到,我们已经定义为零点能，当两个氮原子分离时。
