您可以认为它是一项在模型层完成的任务，因为要给数据分类。

在模型中捕获适当级别的详细信息，而不是混合不同的抽象级别。
Capture the appropriate level of details in the models rather than mixing levels of abstractions.
执行该删除操作很困难，因为已经在模型级别上删除了维度信息。
This is a hard removal, as the dimensional information is removed at the model level itself.
也就是说，当导入了一个概要文件，它的原型在模型中就不再有效。
That is, its stereotypes are not available in the model where only the importing profile is applied.
因此，如果您看到图中描述了一些东西，那么您就知道它是在模型中。

在大多数情况下，IBM团队在模型中找到的对象稍加调整就可以用了。
For the most part, the IBM team found objects in the model that could work with a little effort.
因此，在模型中选择什么分解层级就决定了建模器选择暴露什么系统元素。
Thus, choosing what levels of decomposition to include in the model allows the modeler to choose what system elements to expose.

他的成果大多集中在经济主体在模型限制下学习和不完全理性预期这些方面。
Much of his work has focused on agents learning within models and less-than-fully-rational expectations.
为了描述一个参与者，您可能想给它一个名称来精确地反映其在模型中的角色。
To describe an actor, you want to give it a name that accurately reflects its role within your model.
在模型中，您会注意到有三个截然不同的角色，活动的实现要贯穿这三个角色。
In the model, you should notice that there are three distinct roles through which activities are implemented.
在这个例子中，您没有在模型中产生任何文档：或许您应该产生注释。
