古代计时器——水钟

Ancient timing device——water clock

通过对中国古代计时器水钟的原理研究,利用现代的技术和材料制作了水钟.采用2种方式将匀速的水流转化为其他形式变量:一种是水滴计数法,水钟计时时长15min,累计误差6s;另一种是将匀速的水流转换成质量信号,计时时长10min,累计误差2～3s.

According to the principles of Chinese ancient timing device, using modern technology and materials, a water clock was made. This paper mainly introduced two methods, water drops counting （lasts 15 min with an error of 6 s）, and mass to time （lasts 10 min with an error of 2-3 s）.
