摘要：

It is demonstrated both experimentally and theoretically that broken translational and vertical symmetries of a horizontal convection layer heated from below can lead to a qualitatively new effect, namely, the onset of time-dependent convection. In particular, the behavior of a non-Boussinesq fluid in a layer with sinusoidal variation of the horizontal boundaries is studied near onset.
