| Abstract: | The steelyard clepsydra,a special type of clepsydra,had been the chief time-keeping instrument during the Sui-Tang period and the earlier stage of the Northern Song dynasty.According to the record of ancient documents,this paper gives the possible structure of Li Lan's steelyard clepsydra,and demonstrates the principle for the stabilization of average flow velocity. |
