Examples
- A study on the characteristics of reflection spectrum of field of view under night - sky radiation
夜天光下景物反射光谱特性的研究 - The utility model discloses a luminescent computer keyboard key , which comprises : a key body ; a concave groove , which is arranged on the top of the key body and is used for embedding phosphor powder display character layer under night light and transparent protection surface layer ; after embedding into said groove , the surface has a transparent protection layer with thickness leveled as top face of the key body
本实用新型公开了一种夜光计算机键盘按键，该按键结构包括：键体；键体顶面设置的供镶嵌荧光粉夜光显示字符层及透明保护表层的凹槽；具有镶入所述凹槽后，其表面与键体顶面平齐的厚度的透明保护层。 - ( 3 ) the spectral matching factor of nea phothocathodes for reflecting spectrum of objects under night sky radiation has been studied . the spectral matching factors of typical phothocathodes , such as gaas nea photocathode , s _ ( 251 ) and s _ ( 252 ) photocathode , are calculated and compared . the factors give the explanation of high detection performance of the low - light - level night vision equipments
( 3 )研究了nea光电阴极和夜天光照射下景物反射辐射的光谱匹配系数，计算了gaasnea光电阴极的光谱匹配系数，并将之与s _ ( 251 ) 、 s _ ( 252 )光电阴极的计算结果作了比较，揭示了三代微光夜视仪具有优良探测性能的原因。 - The utility model discloses a luminescent computer keyboard key , which comprises : a key body ; a concave groove , which is arranged on the top of the key body and is used for embedding phosphor powder display character layer under night light and transparent protection surface layer ; after embedding into said groove , the surface has a transparent protection layer with thickness leveled as top face of the key body
