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。
-
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。
-
Well, I guess it's the problem that people who teach the eighteenth-century novel always have, or the Victorian novel: the Victorian novel like the triple-decker, the three-volume novel.
好吧，我猜这个问题是,讲授十八世纪小说,或维多利亚时期小说的人经常遇到的：,像维多利亚时期的三层小说，三卷本小说。

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
-
So the partial pressure or the pressure by which you have this triple point, happens to be 6.1 times 10 to the minus 3 bar.
而要小得多,事实上，水的三相点时的压强是6。1毫巴。
-
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
-
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。
-
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。
-
This is to get the feel of the duple and the triple. So see what you can do.
这两个动作,能让你亲身感受两拍和三拍,试试看吧
-
That is a good solid triple bond.
这是很好的固态三线态。
-
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。
-
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 it looks a lot less messy if we just draw our Lewis structure like this for h c n, where we have h bonded to c triple bonded to n, and then a lone pair on the nitrogen there.
这看起来整洁了不少,如果我们把氰化氢的路易斯结构画成这样的话，这样我们就有氢与碳之间的单键和碳与氮之间三键，然后还有一对孤对电子在氮这里。
-
Occasionally, you get things written in triple meter and in a minor key--minor key.
偶尔,有一些是由三拍子,和小调组成
