和几何单反射椭圆模型。
简单反射代理，根据其当前的感知采取行动。
Simple reflex agents, which act based on their current perceptions.
密闭箱和宽带单反射带通是效率最差的设计。
The sealed enclosure and the wide-bandwidth single-reflex bandpass are the least efficient designs.
其实，挡光板及其上的开孔都是不必要的；单单反射镜本身就可以起小孔的作用。
Actually, the mask and openings are not really necessary; the mirror alone could serve as aperture.
单反射镜结构转台中，通信光先经反射镜反射，再配合方位、俯仰方向的角度调整，实现光轴的精确对准。
In the process of work, the laser was reflected by the mirror at first, then turntable adjusted the reflection direction through changing the Angle of azimuth and pitching for accurately pointing.
带宽相当窄的单反射式带通箱也有能够拥有好的瞬态特性，但是再次强调，不可能赶上最优化的密闭箱体。
Single-Reflex bandpass designs can also have good transient characteristics if their bandwidth is fairly narrow, but again, not as good as an optimized sealed enclosure.
从箱体阻尼损失来看，导向孔和双反射带通箱设计在极低频下比密封箱和单反射式带通箱设计有着更大的失真。
Related to the loss of enclosure damping, ported and dual-reflex bandpass designs also exhibit higher distortion levels at very low frequencies than sealed or single-reflex bandpass designs.
