covalent bonds
基本解释
- [物化] 共价键（原子间通过共用电子对形成的化学键）
英汉例句
- 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。 - 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。 - At this level, basic concepts such as bonding, ionic and covalent bonds are briefly introduced to students.
在这一级，基本概念，如氢键，离子和共价键简要介绍给学生。 - There's not actually chemical covalent bonds that are formed but it's a non-covalent interaction, usually dominated by hydrogen bonding.
所以配体和受体之间不生成共价键,这是一种非共价化合反应,它们通常以氢键相联
耶鲁公开课 - 生物医学工程探索课程节选 - 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。
麻省理工公开课 - 化学原理课程节选 - 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。
麻省理工公开课 - 化学原理课程节选 - They performed this trick, as they explain in the journal Langmuir, using a substance called phenyl azido, which readily forms covalent bonds with its neighbours when exposed to ultraviolet light.
