The entire ring has about 1000 magnets spaced at regular intervals . 整个圆环由大约1000个磁铁组成，它们按着一定的间隔排列。
2.
A series of small linearly spaced holes or cuts on a form to facilitate tearing along a desired line 在表格纸上，为便于沿指定线撕开而设计的一连串以小间隔排列成线状的穿孔或缺口。
3.
The process that light wave gets through arrayed waveguides can be regarded as a process of extracting spatial sample and filtering spatial frequency . spacial sample is accomplished by period interval arrangement of awg and spatial frequency filtering is accomplished by the fundamental mode and phase delay of each arrayed waveguide which is just a spatial frequency filter 而光场通过阵列波导的过程，可八硕士学住论文waiaster ’ stiesis以看作是空间抽样以及空间滤波的过程：空间抽样由阵列波导的周期间隔排列完成，空间滤波由每个阵列波导的基模形式以及位相延迟完成（阵列波导即为一空间滤波器） 。
