摘要：

The time evolution of a wide variety of physical systems exhibiting two-dimensional cellular structures has recently been studied and found to lead to a universal distribution x(l) of the number of sides, l, of the cells. A simple model for the evolution of these structures is presented and analysed. The model exhibits a one-parameter family of fixed-point distributions x(l)*(sigma). Within this model, universality is maintained by a mechanism in which a particular marginally stable fixed point is selected. The predictions of the model compare well with experimental observations in soap froths.
