For most optical systems, it is assumed that the transmitted wavefront has uniformamplitude and constant polarization state across the exit pupil.
在一般的光学系统设计中，都假设光线服从几何光学规律，认为系统会均匀地传播所有的偏振态。

Objective To investigate the effect of uniformamplitude medium frequency sinusoidal electrotherapy on learning and memory impairment induced by hypobaric hypoxia in mice.
目的探讨等幅正弦中频电疗法对急性低压缺氧引起的学习记忆障碍是否有保护作用。

A new resonant sensor consisting of two resonators of uniform structure and size is presented. The closed loop control system is composed of two amplitude controllers and an inverter.
