<正> 在可见光谱范围内(380nm-780nm)。人眼对不同波长的辐射,即各种颜色光,具有不同的感受性。一般说来,人眼对可见光谱中黄绿色的感受性最高,对光谱两端的红色和紫色,感受性就低得多。人眼对光谱不同区域视觉感受性不同的这种特点,通常叫作光谱视亮度或光谱感受性,并以其函数来表征,称为光谱相对视亮度函数。它的图示,就是

This study was undertaken by using the flicker method with 50 normal visionadult subjects. The visual field subtended two degrees and the level of luminancewas 30 cd/m~2. 18 points, with seperations of 10 or 20 nm, were selected for measure-ment in the wavelength range of 404 to 700 nm. Subjects of two age groups wereused: below 30 and above 30 years of age. The results obtained were as follows. First, the average maximum spectral sensitivity of 50 subjects, was found to beat 555 nm, which is in close agreement with the CIE V_λ. Most of the subjects had amaximum value at 555nm or 560nm, which showed that it is considerably concentra-ted. Furthermore, another verification of the maximum value was made, the resultagain was proved to be valid. Sceond, comparison was made between the two age groups. It indicates thatthere is a variation with age in the short wave and of the spectrum, where the V_λ va-lue smoothly decreases as age increases. Third, at the extreme short wavelength end of the spectrum (below 460 nm), therelative sensitivity obtained by the present study is significantly higher than that ofCIE, it is rather coinciled with the result revised by D. B. Judd in 1951. Fourth, aside from the deviation mantioned above, the shape of the ralative spe-etral Iuminosity curve of Chinese people is basically similar to the CIE V_λ. This fin-ding in turn suggests that there is likely no significant ethnological difference betweenwhite and yallow races in this respect.
