由于巨大的重量向下压岩层，使它趋于在它的薄弱处向下折叠，这最终导致地壳的实质断裂。

Because of the great weight pressing down on them, these layers tend to fold downward at weak spots, and this finally causes an actual break in the crust.

因此，我们建议进行以下压力测试过程。

Therefore, we recommend the following stress testing procedure.

But because there's this lone pair here, it's pushing down on the other bonds, 5° so we end up with an angle of less than 109 . 5 degrees.

但因为这里有孤对，它会把其它键向下压，所以键角会小于109。

So since we have two lone pairs, we're going to be pushing down even further on the bonding electrons, so we're going to smoosh those bonds even closer together.

因为我们有了两个孤对，我们会把成键电子,更加向下压，所以我们把这些键更加紧得推到一起。
