1·And the key word for covalent bonds is the idea of being Shared.
而关于共价键最关键的一点就在于共用的概念。
2·So specifically, today we're going to talk about covalent bonds.
特别地，今天我们要专门讲一讲共价键。
3·So, that's basically the idea of how we are going to be thinking about covalent bonds.
那么，这就是我们所应该想到的基本思路，在考虑共价键时。
4·Both ionic and covalent bonds arise from the tendency of atoms to attain this stable configuration of electrons.
离子键和共价键都是由于原子要达到这个稳定电子构型而形成的。
5·So as we said when we first introduced covalent bonds, it's a sharing of electrons, but it's not always an equal sharing.
当我们刚开始介绍共价键的时候，我们说过电子是被共用的，但是共用却不一定是均等的。
6·Linear-dendritic hybrid copolymers are a special type of copolymers composed of both dendritic (d) and linear polymer blocks (l) which are linked together by covalent bonds.
线形-树状体杂化嵌段共聚物是由树枝状高分子嵌段(d)与线形高分子链(L)通过化学键连接而成的一类特殊拓扑结构的共聚物。
7·The strong covalent bonds along the fiber's length give them a very high modulus in this direction because to break or extend the fiber the bonds must also be broken or moved.
沿着纤维长度有很强结合力的共价结合在这个方向上给予复合材料很高的模量，因为要损坏或拉伸纤维就必须破坏或移除这种结合。
8·SILANE organo-silane polymers react at room temperature with hydroxides present in the metal oxide layer of cleaned metal substrates to for strong covalent bonds with the metal substrate.
金属表面经过清洗后，硅烷产品在室温下能与其氧化层中氢氧化物反应，形成很强的共价键。
9·And when we talk about covalent bonds, there's 2 properties that we'll mostly focus on, and that's going to be thinking about the bond strength or the energy by which it stabilized when it bonds.
而当我们讨论共价键的时候，有两点特性是我们最关注的，那就是键的强度，或者说成键之后能量降低了多少。
10·An organic coordination (complexing) compound in which the metal ion is bound to atoms of nonmetals, e. g. nitrogen, carbon, or oxygen, to form a heterocyclic ring having coordinate covalent bonds.
一种配位(络合)化合物，其中的金属离子与氮、碳或氧等非金属原子结合生成有配位共价键的杂环。
