摘要：

We conduct numerical simulations on a simple model of a two-dimensional steady-state sheared foam, and define a quantity Gamma that measures stress fluctuations in the constant-area system. This quantity reduces to the temperature in an equilibrium system. Wie find that the relation between the viscosity and Gamma is the same as that between viscosity and temperature in a very different system, namely a supercooled liquid. This is the first evidence of a common phenomenon linking these two systems.
