在本实验中，使用一个微型房间，研究了照明度对舒适视觉环境的影响。这个房间被布置得像一个普通的办公室。光源被放置在由不透明的丙烯酸板制成的天花板上方。这个房间是通过天花板照明的，使用六种灯。在不同的照明条件下，要求被试根据心理学方法对办公室进行评价，该方法包括“图像”和“评价”测试。对于每个测试，通过连续分类法获得的标度值进行主成分分析。作为分析的结果，“图像“和“评价“测试均提取了四个分量，分别占95（cid：631）（cid：631）和90（cid：631）（cid：631）。应用典型相关分析表明，两种测验之间的相关性很强。在这两种测试中，第一分量与照度、色温和显色性密切相关，第二分量与照度有很强的依赖性。和照度进行了讨论。
In the present experiment, the effects of illuminance upon comfortable visual environments of a room were examined by using a miniature room. The room was set to simulate an usual office. The light source was placed above the ceiling made of opaque acrylic plate. The room was lighted through the ceiling, using six kinds of lamps. Under various lighting conditions, subjects were required to rate the office according to the psy-cological method, which consisted of the " image " and " evaluation " tests. For each of the tests, the scale values obtained by the method of successive categories were subjected to principal components analysis. As the results of the analysis, four components were extracted for both the " image " and the "evaluation " tests accounting for 95(cid:631)(cid:631) and 90(cid:631)(cid:631) res-pectively. The canonical correlation analysis was, applied and indicated that the relation between two tests was very strong. In both tests, the first component closely related to illuminance, color temperature and color rendering, and strong depencence of the second component upon illuminance was found. The relationships between the scale values:of individual items. and illuminance were discussed.
