对于我们个人来说,时间更多的还是表现在钟表上……历史篇日晷是最早报“标准时”的仪器,它由晷盘和晷针组成。晷盘是一个有刻度盘,其中央装有一根与盘面垂直的晷针,针影在盘上的位置随太阳运转而移动。古埃及钟表巧匠制作了装有指针和鸣击装置的钟表。这种钟表每隔一小时,一定数量的圆球便滚落到金属盖上,发出大声鸣响。 For us personally, more time is still manifested on the clock... The history chapter is the earliest report of the “standard time” instrument. The sampan plate is a dial with a pin in the center perpendicular to the plate surface. The position of the pin shadow on the plate moves with the sun. Ancient Egyptian watchmakers made watches equipped with hands and tweeters. Every hour of this kind of timepiece, a certain number of balls roll down onto the metal cover and make a loud noise.
