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

在氢键里，氢原在原也被不平等共享。

But it compensates with a huge number of hydrogen bonds.

但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。

And so hydrogen bonds are incredibly important.

所以氢键是非常重要的。

And the most famous one is called hydrogen bonds.

其最着名的是氢键。

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。

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

它们被周围的氢键牢牢地固在原地。

Now a specific type of dipole-dipole is going to be a hydrogen bond.

现在，偶极-偶极的特是氢键。

Hydrogen bonds are going to form when we have hydrogen bonded to either oxygen, nitrogen or fluorine.

当氢与氧、氮或氟结合时, 就会形成氢键。

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

但冰的单个水分将比液态水具有更多的氢键分。

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

氢键快速形成再断开，就好比是高生的关系，真的是速战速决。

Hydrogen bonds are going to occur, lots of people think it's between hydrogen and something else.

氢键将会发生, 很多人认为它是在氢和其他东西。

And so in water we have hydrogen bonded to oxygen.

因此在水，氢与氧形成键。

One hydrogen bond looks like this.

一个氢键是这样的。

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，被称为双螺旋结构。

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。

Now let me show you where the hydrogen bond is.

现在让我告诉你氢键在哪里。

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，水分有一种独特的的相互作用叫做氢键。

So hydrogen bond is going to occur when we have hydrogen bonded to either a nitrogen, oxygen or a fluorine.

因此, 当氢与氮、氧或氟结合时, 就会发生氢键。

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

但温度低于4 度时，水分的动能开始跌落低于氢键内能源量。
