Hydrogen bonds form and break like high school relationships, that is to say, quickly.

氢键快速形成再断开，就好比生之间的关系，真的速战速决。

But it compensates with a huge number of hydrogen bonds.

它通过大量的氢键进行了弥补。

Hydrogen bonds are so strong that it takes a lot of energy to break them.

氢键非常强大，需要大量的能量才能打破它们。

One hydrogen bond looks like this.

一个氢键这样的。

In a hydrogen bond, a hydrogen atom is shared, also unequally, between atoms.

在氢键里，氢原子在原子之间也不平等共享。

They're held in place pretty rigidly by all the hydrogen bonds surrounding them.

它们周围的氢键牢牢地固定在原地。

So, hydrogen bonds form much more frequently than they break and beautiful structures start to emerge from the chaos.

所以，氢键形成比断开还频繁，混乱，开始呈现出新的美妙结构。

But a single water molecule in ice will have more molecules hydrogen bonded to it than in liquid water.

冰的单个水分子将比液态水具有更多的氢键分子。

But below 4 degrees, the kinetic energy of the water molecules starts to fall below the energy of the hydrogen bonds.

低于4 时，水分子的动能开始跌落低于氢键内能源量。

Water has a special kind of interaction between molecules that most other substances don't have, and it's called a hydrogen bond.

水，同大多数其他物质不同，水分子之间有一种独特的的相互作用叫做氢键。

The bases pair up, forming hydrogen bonds, and the DNA forms a twisted shape that is known as a double helix.

碱基配对，形成氢键，DNA 形成扭曲的形状，称为双螺旋结构。

The nucleotides on one strand pair up using hydrogen bonds with nucleotides on the opposing strand to create the double-stranded DNA.

一条链上的核苷酸通过氢键与相对链上的核苷酸配对，形成双链DNA。

Water, for example, is very well-known for its tendency to form hydrogen bonds.

例如，水因其形成氢键的趋势而广为人知。

Urea breaks hydrogen bonds between molecules.

尿素破坏分子间的氢键。

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

这称为氢键 —— 液态水的单个分子只会通过氢键与其他一些水分子结合。

As we heat these saturated fats up, slowly, we can disrupt those hydrogen bonds and turn to liquid, called rendering and is delicious.

当我们慢慢加热这些饱和脂肪时，我们可以破坏这些氢键，变成液体，这叫做炼脂，很美味。

In a single drop of water, hydrogen bonds form extended networks between hundreds, thousands, millions, billions, trillions of molecules, and these bonds are constantly breaking and reforming.

一滴水里，数百、 数千、 数以百万，数十亿，数万亿的分子之间，氢键由此而形成大范围网络，这种连接又不断地断开再重新形成。

But up here on the surface, these water molecules don't have as many hydrogen bonds holding them in place and they're able to sort of roll around.

在表面上，这些水分子没有那么多的氢键将它们固定在原地，所以它们能够滚动。

The negatively charged oxygen atom from one molecule is pulled towards the positively charged hydrogen atoms of another, creating a strong attraction known as a hydrogen bond.

一个分子带负电的氧原子会另一个分子带正电的氢原子吸引，形成了强大的吸引力，即氢键。

Here's an example from Watson and Crick's famous paper on the structure of DNA. They say, the hydrogen bonds are made as follows.

这沃森和克里克关于DNA结构的著名论文的一个例子。他们说，氢键的构成如下。
