We call the bonds between these atoms covalent bonds.

我们将这些原子之间键称作共价键。

Now, remember that in a covalent bond two electrons are shared, usually unequally, between atoms.

那么，通常，在共价键里，两个电子在原子之间被不平等共享。

Those crosslinks are generally also formed from covalent bonds, which are interactions where atoms share electrons and generally require a chemical reaction to make or break.

这些交联键通常也是由共价键形成，这些共价键是在原子共享电子相互作用下形成，通常需要化才能使之形成或断裂。

SPNs do often contain conventional polymers that are held together by covalent bonds.

SPN通常含有由共价键连接在一起普通聚合。

For example, take molecules, atoms held together by covalent bonds.

例如子中原子有着共价联系。

Normally, different molecules are connected by covalent chemical bonds between their atoms.

通常情况下，不子通过原子间共价化键相连接。

Diamonds are hard because of their molecular structure, each carbon atom forms four covalent bonds with the atoms around it, which forms an exceptionally hard crystal structure.

金刚石坚硬是因为其子结构，每个碳原子与相邻原子形成四个共价键，从而形成极其坚硬晶体结构。

Columns of transition metals Compounds are created either by unpaired electrons from different atoms forming joint orbitals called covalent bonds or by the complete transfer of unpaired electrons between atoms to create paired orbitals in the recipients.

过渡金属列化合是通过不原子未配对电子形成称为共价键共轨道，或者通过原子之间完全转移未配对电子，在接收方中形成配对轨道而产生。

Normally, different molecules are connected by covalent chemical bonds between their atoms. But Sauvage and his team used copper ions to coax molecules into interlocking like links in a chain, which they call a catenane.

通常，不子通过它们原子之间共价化键连接在一起。但索瓦日和他团队使用铜离子促使子像链条中环节一样相互扣合，他们称之为环烷。

Inside the quartz is a crystal lattice of one silicon for every two oxygen atoms, which forms a network of covalent bonds, with electrons being more attracted to the oxygen due to their electronegativity.

石英内部是由每个硅原子对两个氧原子组成晶格，形成了一个共价键网络，由于氧电负性更强， 电子更倾向于被氧吸引。

They're going to have one electron that they tend to use when they are either getting lost to form an ion or that they might be able to use to form a covalent bond.

它们有一个电子，当它们要么失去电子形成离子，要么可能使用这个电子形成共价键时会用到这个电子。

Really though, hydrogen bonds aren't chemical bonds in the same sense that ionic and covalent bonds are, but they are the strongest interactions that occur between molecules.

真， 氢键并不是像离子键和共价键那样化键，但它们是子之间最强相互作用。

The very fact any student in America knows what a covalent bond is is a fucking miracle, and every adult involved deserves the Congressional Medal of Honor.

美国生竟然知道什么是共价键， 这简直是个奇迹，所有参与其中成年人都值得获得国会荣誉勋章。

To turn nasal spray into meth, you’d need to first break its very strong covalent bonds, and that requires dangerous reagents and expensive, high-pressure lab equipment.

要将喷鼻剂变成冰毒， 您需要首先打破其非常牢固共价键，而这需要危险试剂和昂贵高压实验室设备。

So like in a covalent bond, two electrons are equally shared between two atoms, and that sharing of electrons is what keeps them close together.

在共价键中，两个电子在两个原子间被等地共享，这种电子共享是使它们紧密结合在一起原因。

In this case it's just a covalent bond and more specifically we call that a peptide bond because it's between two peptides.

在这种情况下，它只是一个共价键，更具体地说，我们称之为肽键，因为它连接着两个肽。

The atoms are all of the same element and they're all bonded together with covalent bonds, so what's the difference?

原子都是一种元素， 它们都是用共价键结合在一起，那有什么区别呢？

Be careful because we've got covalent attachment, and coordinating to metal sites.

要小心，因为我们有共价连接，并与金属位点协调。

And that's enough to have a polar covalent bond.

这就足以形成极性共价键了。

What we have are a series of amino acids that are attached together through covalent bonds.

我们所拥有是通过共价键连接在一起一系列氨基酸。
