摘　　要：首先介绍了国际标准组织在教学中显示设备尺寸与观看距离关系的研究。然后一方面结合汉字的特点与人眼视觉特性进行了理论推理与计算,另一方面开展了主观评价试验。实验结果与理论推理具有较高的相关性,都说明了:当PPT常用最小字号为16号,最远观看距离与显示屏幕高度的具有正比关系,在进行"会形学习"时,不宜超过3.0倍;在进行"会意学习"时,不宜超过6.7倍。Firstly, this paper introduces the research of the international standard organization about relationship between the size of the device and the viewing distance. Then, on the one hand, the theoretical reasoning and calculation was carried out combining the characteristics of Chinese characters and human visual characteristics, on the other hand, subjective evaluation experiment was carried out. The experimental results have a high correlation with theoretical reasoning. Both of them indicated： when 16pt was used as the minimum font size in PPT, the fast viewing distance is proportional to the height of the screen display, in the ＂ copy studing＂ , not more than 3 times ; in the ＂associative learning＂ , not more than 6.7 times.
