求翻译：如此轮流，使每位分时显示该位应显示字符。段选码、位选码每送入一次后延时一秒，因为人眼的视觉暂留为0.1s，所以每位显示时间间隔不能超过20ms，并保持延时一段时间，以造成视觉暂留效果，给人看上去每个数码管总在亮。是什么意思？

Such a rotation, so that each time-sharing display this bit should be displayed characters. Segment selector for code selected code each into a delay of one second, because the human visual persistence for the 0.1s, so each time interval can not be more than 20ms, and to keep the delay period of tim

This rotation, so that each sub-displays the characters should be displayed. Select paragraph code, place a check mark after each feed into a one-second delay is because the human eye visual park is 0.1 s, so that each time interval cannot be more than 20Ms latency and to maintain a period of time i

So in turn, causes when each rank demonstrated this should demonstrate the character.Duan Xuanma, the position choose the code to send in every time a from now on time delay for second, because the human eye persistence of vision is 0.1s, therefore each demonstration time-gap cannot surpass 20ms, an

In turn, each position shows that the characters should be displayed. Duan Xuan into the code, selection code every time delay after a second, because of the persistence of vision of the eye are 0.1s, so each display interval cannot be less than 20ms, and keep the delay for a period of time, to caus
