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.

本文给出这类系统的参数递推辨识算法，克服了迭代算法不能在线运行、需反复矩阵求逆的不足。

This paper presents a recursive parameter identification algorithm for the system. Compared with the iterative algorithm, it can avoid the matrix inversion and can be operated on-line.

通常，制订项目进度计划是一个反复迭代的过程，该过程确定每个活动和每个里程碑的开工日期和完成日期。

Developing the project schedule is often an iterative process. It determines the planned start and finish dates for project activities and milestones.

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。
