Notice the application of multiplicities in Figure 11.

看一下图11中应用程序的复合度。

You'll note that I don't show the reverse multiplicities in Figure 5.4.

可能你注意到，在图5.4中，我没有显示反向的一对多关系。

A one-to-one association is one in which the maximums of each of its multiplicities are one.

一对一关联就是它的每个复合度的最大值都是1的这么一种关系。

Here, you'll focus on one-to-one and one-to-many multiplicities, which you'll handle as a single case.

这里你将集中于一对一和一对多的多重性，你将把它们作为单一的用例处理。

Furthermore, computing the right multiplicities can be challenging in models with more complex fork-join structures.

而且，在一个使用更复杂的fork - join结构的模型中，要计算出正确的增殖次数也并非易事。
