当压力释放后，平面型化学键恢复，零散的碳原子又回到了它的柔软的玻璃形态。

When the pressure was released, the flat bonds returned, and the odd carbon turned back to its pliable, glassy form.

属性文件是平面文件—它们并未提供任何形式的键嵌套和分组—但是您可以通过创建具有相同前缀的带点名称来对您的键实现虚假嵌套。

Properties files are flat - they don't offer any sort of nesting or grouping of keys - but you can pseudo-nest your keys by creating dotted names with identical prefixes.

相反，石墨的柔软和易滑脱特性源于它的碳原子形成了“平面的”化学键，导致了三明治式的层片状原子，而层间吸引力很微弱。

By contrast, graphite is soft and slippery because its carbon atoms form "flat" bonds, resulting in sandwiched sheets of atoms that weakly attract one another.

So what we'll have here is a trigonal planar case, and you can see that we only have three electrons that are set for bonding, so we'll add three hydrogens, and for b h 3, we'll get a stable structure here.

让电子劲量远离的时候，不用考虑它,这个例子是平面三角形，你可以看到，只有3个电子可以成键。

So if you picture, for example, b h 3, it's going to look like this.

如何使键劲量相互远离，我们会有平面三角形的情形，如果你想象。

So again, if we think about that shape of that carbon atom, it's going to be trigonal planar, 120° it's going to have bond angles of 120 degrees, because we have this set up of having three hybrid orbitals.

如果我们考虑碳原子的形状，它是平面三角形，键角是，因为我们有这三个杂化轨道。
