考察了人对显示在阴极射线管（ＣＲＴ）显示器屏幕上的静态汉字和运动汉字的认知能力。结果为：（１）显示时间由５ｓ增至６０ｓ，静态屏显汉字的认知量由１０．２个提高到１０９．９个，视觉通道传递量由７７．５ｂｉｔ提高到８３５．２ｂｉｔ，建立了两者与显示时间相关的数学模型和认知不同数量静态屏显汉字所需显示时间的估算公式；（２）汉字行移动速度由０．６３行／ｓ提高到２０行／ｓ，动态屏显汉字的认知量由６０．４个降至１．２个，视觉通道信息传递量由４５９ｂｉｔ降至９．１ｂｉｔ，建立了两者与汉字行移动速度相关的数学模型；（３）低于６．６７行／ｓ的不同汉字行移动速度时的运动汉字单位时间的认知量无显著性差别；（４）汉字笔划愈多，汉字认知量及视觉通道信息传递量愈小
Examined the cognitive ability of humans for both static and moving kanji displayed on a cathode ray tube (CRT) display screen. The results were as follows: (1) The display time was increased from 5s to 60s, the cognitive capacity of static screen displaying Chinese characters increased from 10.2 to 109.9, and the visual channel throughput increased from 77.5bit to 835.2bit (2) the moving speed of Chinese character line is increased from 0.63 line / s to 20 line / s, and the dynamic screen display is both the mathematical model related to display time and the estimation formula for recognizing the display time of different numbers of static screen displaying Chinese characters; The number of Chinese characters decreased from 60.4 to 1.2, and the visual channel information transfer rate dropped from 459bit to 9.1bit. Mathematical models were established to correlate the two with the moving speed of Chinese characters. (3) .67 lines / s different Chinese characters at the moving speed of the movement of Chinese characters per unit time, the amount of cognitive no significant difference; (4) Chinese stroke more, the amount of cognitive Chinese characters and visual channel information transfer smaller
