It is breathtaking. The new administration's budget for next year alone calls for a $1.2 trillion deficit nearly triple any past federal deficit,".

Well, that's a beat of basically a duple meter with a triple subdivision, but we're not getting into triple subdivisions here.
这就是个典型的二拍子,伴随一个三拍子的进一步划分,但我们这里不讨论三拍子的进一步划分
So this unique temperature and unique pressure defines a triple point everywhere, and that's a great reference point.
这样,无论在何处,三相点都具有相同的温度和压强,十分适合来作参考点。
tax evasion charges. In U.S.horse racing,there was no Triple Crown winner - again.

Let's re-draw this, so it looks a little bit neater, where we have a triple bond in the middle instead, and again, we need our negative 1 charge there.
让我们重写这个,这样看起来更整洁一点,我们有一个三键在中间,同样地,我们这里需要一个负电荷。
Yargeris Savigne of Cuba came out on top in the triple jump with a leap of 14.95 meters, while Spain's Marta Domnguez took the gold medal in the 3,000 meter steeplechase, with a world leading time of 9 minutes,7.32 seconds.

Now it's not uncommon, by the way, for laboratory animals in these studies to triple their body weight.
顺便说下,在实验室,让动物体重变成普通的三倍,并不罕见
U.S.officials say there was spontaneous applause at the meeting, at a New York hotel, when word arrived of Senate approval of the five-year Pakistan aid plan, which would triple civilian U.S.assistance to about Expected to win final approval in the U.S.

I lucked into it but I'd certainly encourage everybody to get a little bit of a flavor of the people's side, the language of business, and the science. I think that's the let me call it "the triple crown of preparation."
我有幸进入这个行业,但是我经常鼓励,人们从他人的角度思考看看,思考商业语言和科学,之间的关联,我想这应该叫,“准备阶段的三重加冕“
Let's do a triple meter one. Here we go.
再来一个三拍子的,开始
So let's take the case of acetylene where we have two carbon atoms that are going to be triple bonded to each other, each are bonded to a carbon and then to one hydrogen.
让我们来看一看乙炔的例子,我们有两个碳原子,成三键,每个碳和一个碳一个氢相连。
So, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.
比如,在这下面我写的是氮分子2,而这个是氢分子,但我在上面把这些分子的形式改写了,大家可以看到,这是一个氢与氢之间的单键,含一个氮与氮之间的三键。
They're not showing them keeling over from a triple bypass surgery, let's say.
当然广告里没放他们,免于三重心脏搭桥手术画面
And the triple point of water is 16K that temperature and pressure - there's a unique temperature and pressure where water exists in equilibrium between the liquid phase, the vapor phase, and the solid phase.
与水的三相点,我们定义它为273。,水的三相点,是一个特定的温度和压强,可以使水的液态,气态和固态三相共同达到平衡,三相点是液态。
So now let's think about a triple bond.
现在我们来看看三键。
That's why we hear a triple pattern here.
这就是为什么我们会听到三拍
How many think it's in triple meter? Okay.
多少人认为是三拍子呢,很好
It adds fifty percent or a half to that and that means instead of two quarter notes that we now have three and we can do the same thing to any one of these other values here and that's how we get our triple relationships.
加上了百分之五十或者说一半的原音符值,这意味着除了有两个四分音符,我们现在有三个了,我们也可以在其他这些音符值后加上附点,这就是我们如何做到三倍形式的安排的
N 2 So any chemist should be able to just look at n 2 and know that it's a triple bond, but that's not something that we've learned how did to do yet, so let's go ahead and start a new topic that's going to allow us to have some sort of sense of what the valence electron configuration, which includes whether something's a single or double or a triple bond can be figured out for any given molecule.
任何一个化学家都应该能够仅仅通过看到2,就知道它有一个三键,但是我们还没学习如何做到这点,因此下面我们就开始进入一个新的主题,它将使我们能够有一定的认识,对于价电子的排布情况,包括可以对任何一个给定分子中的键是单键双键,还是三键作出判断。
So let's think about how we can classify single and double and triple bonds, which is what we're really used to dealing with in terms of these sigma bonds and these pi bonds.
让我们想想怎么来分类单键双键,和三键,这在我们在考虑sigma键,和π键是很有用的。
And so the slope of this thing is f at the triple point, which is this point here, this is the temperature of the triple point of water, f divided by 273.16. That's the slope of that line.
除以x轴的坐标,这就是斜率,而直线,经过原点,因此斜率乘上T就得到。
