nea photocathode meaning in Chinese

负电子亲合力光电阴极

In view of the problems existing in the research and producing of the iii image tube in our country , a study of the iii image intensifier have been carried on , the work introduced in this dissertation is as following : ( 1 ) the way to evaluate the properties of nea photocathodes has been proposed . that is using the spectral response and xps measurement results to determine the property parameters of nea photocathodes
本文针对国内在三代管研制方面存在的问题，围绕“三代像增强器研究”作了以下工作： ( 1 )研究nea光电阴极的性能评估，提出通过光谱响应和变角xps测试确定阴极特性参量，从而有效地解决nea光电阴极的性能表征问题。
( 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。
