摘要： 本项工作的目的是核查以线光谱为特征的光源在各种适应亮度(0.75尼特至125尼特)下对于视敏度的影响,结果如下: 1.在四种光源照明下,视敏度随着亮度的增加而增加,当达到一定亮度时,视敏度的增加趋向饱和。 2.以线光谱为特征的光源在同等亮度下视敏度大于以连续光谱为特征的白炽灯。 3.高压钠灯和高压汞灯在各种亮度时的视敏度差异不显著。 4.在7.5尼特—25尼特时四种光源的视敏度差异不显著。

Abstract: The purpose of this study is to examine the .influences of lightsources characterized by linear spectrum on the visual acuity underdifferent adaptation luminances (0.75cd/m~2--125cd/m~2). The results areas follows: 1.The visual acuity under these light sotirces enhanced with theincrease of adaptation luminance, but the increase of visual acuitybecame saturated when the adaptation luminance reached a certaindegree. 2.The visual acuity under sources characterized by linear spectrumis greater than under sources characterized by continuous spectrum, theluminance level remaining unchanged. 3.The difference of visual acuity under high pressure sodiumlamp and that tinder high pressure mercury lamp at all luminance levelsis not significant. 4.The differences between the four sources are not significant atthe luminance levels from 7.5cd/m~2 to 25cd/m~2.
