孔径角
[机] aperture angle
- 在实际应用中，由于聚焦孔径角加大，观测系统范围也必须相应加大，否则经验公式失效。
When the formulas are applied, the scale of the observation system due to the large focus aperture angle must be enlarged, or else the empirical formula will be invalid. - 结果表明，影响偏移成像水平分辨率的主要参数是介质速度、地震子波主频和偏移处理的孔径角。
The main parameters that effect horizontal resolution of migration imaging were identified as medium velocity, dominant frequency of seismic wavelet and aperture angle of migration processing. - 介绍了一种用多模光纤构造的动态光散射粒径测量实验系统，系统中没有对接收光纤的孔径角加任何限制措施。
A dynamic light scattering (DIS) system for particle sizing is described, which is constructed by the use of multimode fibers and without any limits to the angle aperture of the receiving fiber.
