摘要：

The stability of hexagonal convection cells is analyzed in the case of a Boussinesq fluid heated from below with symmetric rigid horizontal boundaries. For P>1.2 a region of stable hexagon convection appears for alpha<alpha(c) and R greater than or similar to 2R(c) where P, alpha, R are the Prandtl number, the wave number, and the Rayleigh number. The theoretical results are in agreement with recent experimental observations by Assenheimer and Steinberg.
