The results of the numerical calculations of oscillations 
of the liquid column free surface under the action on it of axial 
vibration in zero gravity are presented. On the basis of these calculations, 
an analytical model of the surface standing wave named the inertial-capillary 
wave has been developed. Comparison of the analytical calculations 
with the data of the numerical calculations and the experiment performed 
in microgravity under the TEXUS program has been made. The numerical 
study of the thermocapillary convection stability in the presence 
of inertial-capillary waves has shown that the change to the oscillation 
regime is very sharp upon reaching certain values of the vibration 
frequency and amplitude. The heat-and-mass transfer in growing semiconductor 
crystals by the floating-zone method in zero gravity under the action 
of vibration with allowance for the surface waves has been investigated. 
The possibility of measuring vibrational accelerations onboard space 
vehicles by means of oscillations of the liquid-column free surface 
are discussed.
