Abstract: In this paper,Lagrangian method is applied to discuss the problem of the hydrodynamic pressure on a suddenly starting vessel.The free surface profile and the coefficients of the hydrodynamic pressure im the vessel wall are obtained.And it is verified that the singularity of the pressure near the free surface is only logarithmic.-
