我们可以简单的将其设置为一个比较低的值，这就意味着当我们迭代该集合时，数据库将反复查询以获得数据。

We can be lazy and set this to a low value, which means that the database must be repeatedly queried to get data as we iterate over the collection.

服务综合集合的开发总是一个迭代过程，反复经过规格、原型和测试周期。

The development of a complex set of services is always going to be an iterative process, with repeated cycles of specification, prototyping, and testing.

我们也发现我们需要在迭代中期进行检验会议，这 样我们可以问这个问题“在这个反复中我们还需要做多少的工作？ 我们将全部做完么？”

We also found that we needed a mid-iteration checkpoint meeting so we could ask the question, "How much more work have we got to do for this iteration and are we going to do it all?"

N But it's definitely not one and in fact it wasn't N in the case of Selection Sort because remember the algorithm we implemented on stage last week had me going back and forth across the stage selecting on iteration, the smallest person I can find, the smallest number and then putting them into place.

但在选择排序中，肯定不会是1，也不是,注意，上周我们在这儿,实现的算法中，反复地,迭代进行选择，选出最小的数,然后将其放在合适的位置。
