The generation of anticonvection in the presence of heat sources (or sinks)
homogeneously distributed on the interface in layers with finite thickness
, is studied in the framework of linear theory. The general transformation
formula, which predicts the existence of anticonvection in any fluid system
, is derived. This formula is applied to a system of real fluids. (C) 2000
