例如，在大型电子商业表单中，您可以将一些原子对象分组成各节—例如，地址节、付款节和项目节。

For example, in a large e-commerce form, you can group the atomic objects into sections — for example, an address section, a payment section, and an item section.

原子组件是实际的窗口组件，开发人员可用它来填充表单，组合UI组件则可用来对原子对象进行组织和分组。

Atomic components are the actual widgets that developers can use to populate a form, while compound UI components are used to organize and group atomic objects.

并且在持久化对象时，如果它们在相同的实体群中，那么它们只能被持久化到相同的原子事务中。

And when you persist objects, they can only be persisted in the same atomic transaction if they are in the same entity group.
