| 摘 要： | 本文根据光谱匹配系数的表达式，计算了两种Ｓ２５光电阴极与粗糙混凝土的光谱匹配系数。在满月朗星光下，Ｓ２５１与粗糙混凝土的光谱匹配系数分别为０．４８８８和０．２３１８，Ｓ２５２分别为０．７２２４和０．５６３５。并对结果加以分析，说明光谱匹配系数对微光液系统参数有影响，对夜视系统视距的估算有一定的参考价值。

| Abstract: | In this paper according to the formula of spectral matching factor, the spectral matching factors of S 25 photocathodes for rough concrete are calculated, namely 0 488 8 and 0.231 8 to S 251 and 0.722 4 and 0.563 5 to S 252 under full moon and clear star radiation respectively. Through an analysis of the results it is shown that spectral matching factor has influence on the parameters of low light level night vision system, and is of practical value in the evaluation of visual range of night vision systems. |
