【 摘 要 】

The article presents solutions of problems of natural fluctuations of liquid in cylindrical, conical and spherical tanks, with boundary conditions on the free surface and the surface with resistance, i.e. the drain surface. Particular attention is paid to finding the eigenvalues and eigenfrequencies of equations of oscillations of perturbed motion of fluid with the presence of dissipation on the boundary surfaces. It is shown that low speed of lowering of the free surface and resistance conditions on the surface of the drain can affect both the oscillatory and the aperiodic parts of the solution of the fluid oscillation problem.
