摘要：
A system of two layers separated by a diffuse interface which is created due to a phase separation in a binary liquid in the gravity field, is considered. The influence of the density stratification and the gravity on the stabilization of the solution is studied. The stability of two-layer base solutions with respect to long-wave disturbances in the framework of the linear stability analysis is investigated in the case of small density ratio and large Galileo number. It is found that the action of gravity can stabilize the equilibrium state.
