Popis:	The development of convection in a horizontal liquid layer located in a periodically modulated gravitational field (or with periodically varying temperature gradient) is examined. The effect of modulation frequency on stability is studied. Modulation stabilizes equilibrium if the direction of the gravitational force remains constant at all times. In the opposite case, stabilization occurs only at sufficiently high frequencies. In [1] the dependence of the critical Rayleigh number on modulation amplitude of the external force for several fixed frequencies was examined. In all cases examined in [1], the modulation proves to have a stabilizing influence.
