作者们应用语意差别量表和因子分析法研究了青铜器、无釉彩陶和唐三彩等古文物陈列室的视觉环境的最佳照明条件。实验中描述照明条件的参数为:方向性照明的方位角(α)、高度角(θ)和照度矢量/标量照度比(E/E_s)。结果为: 对于青铜器:α=60°,θ=75°,E/E_s=1.00-150; 对于无釉彩陶:α=90°,θ=0°-30°,E/E_s=2.00-2.50; 对于唐三彩:α=30°,θ=75°,E/E_s=2.50-3.00。
The authors applied the semantic difference scale and factor analysis methods to study the optimal lighting conditions for the visual environment of bronze relics, unglazed painted pottery and Tang Sancai and other ancient relics showrooms. The parameters describing the lighting conditions in the experiment were: azimuth angle (α), elevation angle (θ), and illuminance vector/scalar illuminance ratio (E/E_s) of directional illumination. The results are: For bronze ware: α=60°, θ=75°, E/E_s=1.00-150; For unglazed colored pottery: α=90°, θ=0°-30°, E/E_s=2.00-2.50; For Tang Sancai: α=30°, θ=75°, E/E_s=2.50-3.00.
