That is to say brick work in high temperature furnaces, maybe tiles on the Shuttle, to resist high temperatures because of the high internal bonding.
它在能够承受高温炉的温度,例如瓷砖,能够耐受高温,因为它们有强的内部键作用。
It's going to be a stronger bond because it's more stabilized when it when it comes together as a molecule.
这将是一个更强的键,因为它会变得更加稳定,在形成分子之后。
If the bonding energy is very strongly negative, thermal energy isn't great enough to disrupt those bonds and allow those bonds to be broken and then have fluidity.
如果键能非常强,热能并不足以,打破这些化学键,破坏这些化学键,并使它们液化。
And something that we'll see later on is that triple bonds, for example, are going to be stronger than a corresponding double bond or a corresponding single bond.
而我们以后还会看到三键,举例来说,应该更强,相较于相应的双键,或者相应的单键来说。
We can know this information even if we just knew that the bond was stronger, we wouldn't need to look at a graph here, because it turns out that if you have a stronger bond, -- that also means that you have a shorter bond -- those two are correlated.
我们依然可以得到上面的信息,即使我们所知道仅仅是这个键更强,我们不需要去看这个图,因为事实上如果你有一个更强的键,这也就意味着你有一个更短的键-,这两点是互相关联的。
This energy level diagram helps us understand the relationship between electron filling and bond strength.
能级图能帮助我们,理解电子填充,和键强的关系。
Or if we look at how strong it is, it's actually stronger than a single bond, but weaker than a double bond.
或者如果我们看键的强度的话,它实际上比单键更强,而比双键更弱。
That's the huge force that we're talking about in terms of making a bond stable, but there are also repulsive forces, so you can imagine we're going to have electron-electron repulsion between the two electrons if we're bringing them closer together.
正是这个非常强的力,使得我们所讨论的这个键能够稳定存在,但是其中还有排斥力存在,大家可以想象一下,我们会有电子与电子之间的排斥力,如果让它们离得更近。
Strong bonds means the material will resist and applied force.
强键意味着,材料能够承受外力。
Molecular orbital theory, even at this very basic level, allowed us to predict that no, we're not going to see a true bond here, a strong bond.
即使在最基础的层次,分子轨道理论预计,我们不会看到一个键,一个强的键,。
So, if we think about this, which would you say has a stronger bond?
那么,我们来想一想,大家认为哪一个键更强?
Why? Because they have strong bonds.
为什么,因为他们都是强键。
