二聚体与探针之间的引力将二聚体中较低原子向上方拉动，使二聚体从一种姿态切换至另一种。

The attractive force between the dimer and the needle drew the lower atom of the dimer upward, causing the dimer to shift from one position to the other.

他们修饰了一种特殊的硅，其表面覆盖有被称为二聚体的哑铃形原子对。

They tinkered with a particular type of silicon whose surface is covered with dumbbell-shaped pairs of atoms called dimers.

因此，八隅体规则是一条普适的规则，对于所有原子来说都是。

So, the octet rule is a general rule that you'll for all of the atoms.

So, we see is when we use the octet rule to look at fluorine molecule, we're combining two fluorine atoms, and what we end up with is an f f molecule where they're sharing two electrons, so making that covalent bond.

那么，我们看到把八隅体规则用到氟分子上,就是把两个氟原子组合起来，最终得到的氟分子中两个原子,共用一对电子，这就构成了共价键。

So I said that we want to be talking about valence electrons here, so that means if we're talking about, for example, the octet rule for an f f molecule where we have two fluorine atoms, we need to write the valence electrons as dots around them.

我说过我们在这要讨论的是价电子，这就意味着，如果我们要讨论，比如，关于两个氟原子组成的分子的八隅体规则,我们首先需要把价电子画成围绕在它们周围的点。
