STUDY ON HLS ACCORDING TO FLUID MECHANICA THEORY
静力水准系统的流体力学研究

In the light of the fluid mechanics theory,the movement state of liquid in hydrostatic leveling system and the time taken by the system which re-gains the equilibrium of hydrostatics when it has been broken by external disturbances are analyzed.By analysing the relation between the inner diameter of water pipe and the damped oscillation of the water in pipe,the optimal diameter can be chosen in accordance with the range of HLS system.
