Oxygen-Hydrogen bonding is exactly what allows us to turn sugar into energy during respiration.

氧氢键正是让我们在呼吸过程中将糖转化为能量的原因。

This type of bonding is hydrogen bonding.

这种类型的键是氢键。

But polymers within the SPN are crosslinked by more transient intermolecular forces, such as hydrogen bonding.

但SPN内部的聚合物则更多是由瞬态分子间作用力交联的，例如氢键。

It's known as hydrogen bonding — a single molecule in liquid water will only be hydrogen bonded to a few other water molecules.

这被称为氢键 —— 液态水中的单个分子只会通过氢键与其他一些水分子结合。

Let's look at another intermolecular force, and this one's called hydrogen bonding.

让我们看看另一种分子间作用力，这个叫做氢键。

In ice, 100% of O and H atoms are involved in hydrogen bonding.

在冰中，100% 的 O 和 H 原子参与氢键结合。

The polarity of water also results in a phenomenon that makes life possible: hydrogen bonding.

水的极性还导致一种使生命成为可能的现象：氢键。

And this is the situation that you need to have when you have hydrogen bonding.

当你有氢键时，这就是你需要的情况。

And so the three electronegative elements that you should remember for hydrogen bonding are fluorine, oxygen, and nitrogen.

因此，对于氢键，您应该记住的三种负电性元素是氟、氧和氮。

And it is, except in this case it's an even stronger version of dipole-dipole interaction that we call hydrogen bonding.

它是，除了在这种情况下，它是偶极-偶极相互作用的更强大版本，我们称之为氢键。

The way to recognize when hydrogen bonding is present as opposed to just dipole-dipole is to see what the hydrogen is bonded to.

识别何时存在氢键而不是仅偶极-偶极子的方法是查看氢键合到什么上。

When ice melts, there are still about 80% of Os and Hs engaged in hydrogen bonding, creating ice-like clusters that keep the volume of the cold water relatively high.

当冰融化时，仍有大约 80% 的 Os 和 Hs 参与氢键结合， 形成冰状团簇， 使冷水的体积保持相对较高。

Then, there's hydrogen bonding, a special type of dipole-dipole force, one that occurs on polar molecules that contain hydrogen and a strongly electronegative element such as nitrogen, oxygen, or fluorine.

然后是氢键，一种特殊类型的偶极-偶极力，发生在含有氢和强电负性元素（如氮、氧或氟）的极性分子上。

And so the mnemonics that students use is FON. So if you remember FON as the electronegative atoms that can participate in hydrogen bonding, you should be able to remember this intermolecular force.

所以学生使用的助记符是 FON。所以如果你记得 FON 是可以参与氢键的电负性原子，你应该能够记住这种分子间力。

And this just is due to the fact that hydrogen bonding is a stronger version of dipole-dipole interaction, and therefore, it takes more energy or more heat to pull these water molecules apart in order to turn them into a gas.

这只是因为氢键是偶极-偶极相互作用的更强版本，因此， 需要更多的能量或更多的热量才能将这些水分子拉开以将它们变成气体。
