但也有很好的理由来保持这种不愉快的合并状态。

But there are good reasons to keep the unhappy marriage going.

可以通过 MADV_UNMERGEABLE 参数（立即从一个区域取消合并任何已合并页面）从可合并状态删除一个区域。

A region can be removed from the mergeable state through the MADV_UNMERGEABLE parameter (which immediately un-merges any merged pages from that region).

因为它通常以金属的状态存在，并且在地球的冷却和固结的过程中，会优先合并到地核中。

Because it usually exists in a metallic state, it was preferentially incorporated in Earth's core as the planet cooled and consolidated.

So we know we always want to have our systems in as low an energy as possible, so it makes sense that a bond would happen any time we got a lower energy when we combine two atoms, versus when we keep them separate.

我们知道我们总是希望使我们的系统,处于能量尽可能低的状态，因此就应该有化学键产生,一旦我们合并两个原子之后体系的能量变得更低，相较于分开时。
