摘要：
The methods of statistical mechanics are applied to two-dimensional foams under macroscopic agitation. A new variable -the total cell curvature- is introduced, which plays the role of energy in conventional statistical thermodynamics. The probability distribution of the number of sides for a cell of given area is derived. This expression allows to correlate the distribution of sides ("topological disorder") to the distribution of sizes ("geometrical disorder") in a foam. The model predictions agree well with available experimental data. Copyright (c) EPLA, 2010
