主　　题：Water wave radiation Submerged circular cylinder Ice-cover Added mass and damping coefficient. 

摘      要：Using the multipoles method,we formulate the problems of water wave radiation(both heave and surge)by a submerged circular cylinder in water with an ice-cover,the ice-cover being modelled as an elastic plate of very small *** leads to an infinite system of linear equations which are solved numerically by standard *** added-mass and damping coefficients for a heaving and surge problems are obtained and depicted graphically against the wave number for various values of flexural rigidity of the ice-cover to show the effect of the presence of ice-cover on these *** the flexural rigidity and surface density of ice-cover are taken to be zero,the ice-cover tends to free-surface then the curves for added-mass and damping coefficients exactly coincide with the curves for the case of water with free *** it is observed that the added-mass and damping coefficients for the two modes of motion are here also the same.
