Mohr-style pipets are made from glass tubing of uniform bore. Mohr型移液管由孔径均匀的玻璃管制成。
The coddington is essentially a sphere with a slot cut in it to allow an aperture smaller than the pupil of the eye . 科丁顿放大镜实质上是一个球,球面上开槽,使得孔径小于眼的瞳孔。
The results from the pollen densitometers indicate the number of pollen grains sucked into a device per square millimeter of the aperture . 花粉显像密度计的计算结果,可以表明每一平方毫米孔径上吸入的花粉粒数。
In practice the surfaces of interferometer plates cannot be worked perfectly plane, and in consequence the plate separation h always varies over the aperture . 实际上,干涉仪两板表面不可能加工得完全平,因而板的间隔h在孔径范围内总是改变的。
Radio astronomers are now able to synthesize the response of a partially filled aperture of large diameter and thus to map variations in nebular brightness . 射电天文学家现在已经能够把部分充满的大直径孔径进行综合,从而描绘出星云亮度变化图。
