摘要： 本研究在不同背景照度条件下对不同大小、不同对比度的兰道尔环的辨认进行了实验。主要结果表明:(1)视觉作业水平的提高依赖于视标大小、对比度和背景照度这三个变量及其相互间的关系;在视觉作业水平一定时,视标大小、对比度和背景照度存在着两两对应的代偿关系;(2)以中国人为被试的RCS结果与国外欧美人为被试的CIE推荐的结果基本一致,但前者在低亮度范围内要明显高于后者。

Abstract: In the study, the probability of correctly identifying the directionof the gap of landolt was measured. The results were compared withthose of similar experiments. The main conclusions were as follows: (1) The increase of any one of the three variables: the size of thevisual task detail, task contrast and task background illuminance wouldresult in an increase of the level of visual performance, but theincreasing effect on the level of visual performance was reduced as thevalue of the variables increased. (2) When the level of visual performance wes kept constant, therewere compensatory relationships between the size of the visual taskdetail, task contrast and task background illuminance, but thiscompensatory effect was reduced as the compensatory factor wasincreased. (3) The relative contrast sensitivity function of luminance forChinese subjects was very much similar to that recommended by theCIE, but there were some discrepancies in quantity occurring mainlyat the low level of illuminance.
