摘　　要：探究最适投影照度与多媒体教室环境光照度的关系,发现在一定照度范围内,最适投影照度与教室环境光照度的差是一个固定值。该关系可以给投影机的使用、采购和多媒体教室的设计提供数据指导。This research explored the relationship between the most appropriate brightness of projection screen and ambient light in multimedia classroom. Result shows that in a certain illumination range, the difference between the most appropriate brightness of projection screen and the ambient light is a fixed value, which affords data guidance to the use and purchase of projections and multimedia classroom design.

关 键 词：多媒体教室 投影照度 环境光照度
