摘　　要：本文利用Lamb变换,考虑液体的粘性,略去二维Navier-Stokes方程中的非线性项后,建立了频域内Navier-Stokes方程的边界积分表达式,完整地处理了边界条件(包括自由面边界条件和固壁边界条件),并且给出了液体随结构振动时的附加质量与阻尼的计算表达式。In this paper, it established the presentations of boundary integral of Navier-Stokes equations in frequency domain and completed the fullfilment of all boundary conditions including free boundary condition and the constrained boundary conditions, using the method of Lamb transformation, considering the liquid viscosity and neglecting the nonlinear terms in the Navier-Stokes equations. In the paper, it also illustrated the formulations to calculate the additive mass and the damping, when the liquid vibrates with the structure.
