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。
or you can get a triple-triple, which is three meat patties and three slices of cheese.
或者你可以要个“三三”汉堡,里面有三块肉饼和三片奶酪。
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。
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
We see three bonding pairs so this is a triple bond, indeed a multiple bond.
我们看到3对成键电子所以这是一个三重键,它确实是多重键。
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。
This is very easy molecule because we know exactly where to put them without even having to think, we only have one option, and we'll make a triple bond between the carbon and the nitrogen.
这个分子非常简单,因为我们知道应该把它们放在哪里,甚至不用去想,我们只有一个选择,我们将在碳与氮之间形成一个三键。
Both melody and bass could have had a triplet but he chose to have the duple in the bass--the triple up above.
旋律和低音部都可以运用三连音,但是他选择低音两拍,高音三拍
And then we have a triple bond there because we have 3 pairs of electrons.
然后那里还有一个三键,因为我们有三对电子。
And if you hear a triple, your step is this: down-up-up, down-up-up, down-up-up, down-up-up.
听到三拍子时,这样做,强,弱,弱
Let's do a triple meter one. Here we go.
再来一个三拍子的,开始
I just showed you that you can have a single wave, a double, a triple and so on.
我想说的是你能得到单个波,双波,三条波等等。
A triple bond, again is going to have one sigma bond on the internuclear axis.
一个三键,同样的也有沿着核间轴sigma键。
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。
A lot of what we were doing today is very straightforward, the idea of duple versus triple meter, but most modulations we don't usually hear.
我们今天听的很多音乐都没有起伏,包括二拍子,三拍子节奏,但是我们很少听到转调
And something that we'll see later on is that triple bonds, for example, are going to be stronger than a corresponding double bond or a corresponding single bond.
而我们以后还会看到三键,举例来说,应该更强,相较于相应的双键,或者相应的单键来说。
So, if we talked about a nitrogen-nitrogen single versus double versus triple bond, the triple bond will be the shortest and it will be the strongest.
因此,如果我们讨论的是氮与氮之间的单键,双键与三键,那么三键应该是其中最短的一个,同时也是最强的一个。
Is a hydrogen bond shorter, or is a nitrogen-nitrogen triple bond going to be shorter?
是氢的键更短,还是氮与氮的三键更短?
That is a good solid triple bond.
这是很好的固态三线态。
So, in general what we see, and this is always true if we're comparing the same atom, and in general, if we're comparing different types of molecules, but we know that a single bond is always weaker than a double bond, which is weaker than a triple bond.
通常我们会看到,这对比较相同原子来说总是正确的,通常,如果我们要比较不同种类的分子,但我们知道单键,总是要比双键弱,双键总是要比三键弱。
So now let's think about a triple bond.
现在我们来看看三键。
Of course, it's in minor and the voices will come in, but the bass is going, sort of plodding along in a basic duple but with a triple subdivision underneath of that.
当然,它是小调的,人声将会进入,但低音是这样,按基本的二拍子缓慢地行进,但在那下面还用了一个三连音的节奏细分
That's why we hear a triple pattern here.
这就是为什么我们会听到三拍
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。
