摘要
该文对李强就马上漏刻所提出的三种推测进行分析，认为它们的成立均存在困难。因而提出了第四种推测：马上漏刻是一组安装在一块木板上的秤漏。由于马的运动有时可能比较剧烈，这组秤漏难以保持稳定，于是又提出第五种推测：水银从上面的一只玉壶经过一条长而曲折的管道流注到下面的玉壶里。当水银改成弹子时，这就发展成为辊弹漏刻。
Li Qiang made three guesses about the clepsydra on horseback. After analysing these three guesses, this paper holds that there are difficulties for all of them, so it puts forward the fourth guess: This was probably a set of steelyard clepsydras fixed on a board, but as the movement of the horse sometimes gets rather violent, it would be quite difficult for the set to keep balance. Hence, the sib guess is proposed: Mercury flows from a jade pot above into another jade pot below through a long winding tube,and later a small ball is used instead of mercury, resulting in the development of a clepsydra using a rolling ball.
