Infrared sensor lights automatically by infrared emission Angle of the impact of the formation can not be effective in a wide range of sensor space.
红外自动感应灯受到红外发射角度哒影响，无法在较大哒范围形成有效哒感应空间。
In addition, we research atmospheric refraction influence to space-earth satellite communication, and put forward that amending emission Angle can eliminate excursion between beam and satellite.
另外，本文还对大气折射对空地卫星光通信的影响做了研究，提出了利用修正光源的发射角来消除大气折射所引起的光束与卫星之间偏移的思想。
Reduction of the focus hole diameter strongly affects the electrons with large emission angle but its influence on electron focusing is less markedly than the influence of the variations in potential.
减小聚焦极孔径对大发散角的电子有影响，但对聚焦作用的影响不如改变电位明显。
