用"过分简化"来说, 收光圈会增加景深(depth of view), 即焦点准确的影响会下降, 色差是不同色光的焦点位不同引起的, 焦点宽容度增加了, 不同色不对准焦都变了准焦。

Our view is that the depth and length of the current recession relative to previous recessions is closely linked to the tremendous rise in household debt that preceded it.
我们认为相对于以前的衰退,当前经济衰退的长度和深度是与它之前的家庭负债急剧升高紧密相关的。
During each iteration after the first, we create the depth view of requirements by doing deep dives into specific functional areas (use cases), thus building an SRS for each iteration.
在第一次迭代后的每一次中,我们通过深入钻研具体功能领域(用例)来创建需求的深度视角,因而为每个迭代建立一个SRS。
So, in Elaboration, the breadth view of the requirements (the vision) is expected to be unstable, changing as the depth view is understood and executables are created.
所以,在细化阶段,需求的宽度视角(远景)是不稳定的,会随着对深度视角的理解和可执行性的生成而变化。
