摘要：

Non-Boussinesq effects in a Rayleigh-Benard convection system lead to a symmetry breaking between the top and the bottom boundary layers. We have found that the two layers adjust their temperature drops and the thicknesses-lambda such that their temperature scales nu-kappa/g-alpha-lambda-3 are equal, where alpha is the thermal expansion coefficient, g is the gravitational acceleration, and nu and kappa are the kinematic viscosity and thermal diffusivity, respectively.
