的光合作用吸收了太阳能并把它存储在键中。

In part, these PFAS are effective because their chemical bonds are incredibly strong.

在某种程度上，这些 PFAS 有效的原因是因为它们的键非常牢固。

To put it chemistry specific, it has two unpaired electrons, which really want to form chemical bonds.

具体到，它有两个不成对的电子，它们真的想形成键。

And also like graphite and diamond, the different forms that they take are all about bonding differences.

与石墨和金刚石一样，键的差异也会导致不同的网状结构。

Because it's an amorphous solid with bonds of varying strength, glass doesn't have an exact melting point.

因为玻璃是一种由强度不定的键链接成的非晶固体，它没有确定的熔点。

Finally, DNA polymerase fills the gaps on both sides of the union and DNA ligase seals the bond.

最后，DNA聚合酶会填补两侧连接处的空白；DNA连接酶会将键连接起来。

Well, in nature, most things decompose because bacteria breaks down the chemical bonds that hold a substance together.

在自然界中，大多数物质都会分解，因为细菌会破坏将物质结合在一起的键。

And that's the way that the bonds, when they freeze, they actually force the water to have a fixed side.

这就是键，当它们冻结时，它们迫使水有固定的一面。

Right – because gum actually creates a chemical bond – which means when one thing joins firmly to another.

对，因为口香糖实际上会和其他与之接触的物体之产生键，两者会很紧密地粘连起来。

I break the molecule apart, break bonds.

我将分子分解，破坏键。
