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.

在sql术语中，该合并会调用一个外层联系，它会将工作项数据集合中的每一行，与状态数据集合中的单个行使用匹配状态ID来匹配起来。

In SQL terms, this merge calls for an outer join, which matches each row in the work items data set to the single row in the states data set with a matching state ID.

将基线项目中的选择变更合并到未来状态的子工作区，如图 7 所示。

Merge selected changes in the baseline items into the future-state children Workspaces, as shown in Figure 7.

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。
