摘　　要：为了获得中间视觉时光视效能最大值表达式,分别利用异色视亮度匹配法和反应时间法,研究了在中间视觉条件下人眼中的锥状感光细胞和杆状感光细胞对视觉效果的贡献程度,获得了中间视觉时的光视效能最大值表达式,提出了用不同的实验方法得到的结果反映人眼的不同视觉特性,在进行照明计算和评价时,应根据不同的应用和目的,选择相应的光视效能最大值表达式的观点,建议在评价夜景照明效果时宜采用异色视亮度匹配法获得的光视效能最大值,对于道路照明设计,宜采用反应时间法确定的光视效能最大值进行计算。To obtain the expression of maximum spectral luminous efficiency of mesopic level, we studied the contribution to spectral sensitivity in the mesopic region of the rods and cones based on heterochromatic brightness matching and reaction time, respectively. We next acquitted the expression of maximum spectral luminous efficiency of the mesopic level. Our opinion is that the results based on different experiments reflect different vision characteristics of human beings. The expression of maximum spectral luminous efficiency should be chosen in accordance with the application. We advise that the maximum spectral luminous efficiency based on heterochromatic brightness matching should be chosen in evaluating the effect of night scene lighting. The maximum spectral luminous efficiency based on reaction time should be chosen in designing road lighting.
