摘要
The Z-cone model, which provides an analytic approach to the estimation of the energy of a foam for simple crystal structures, has been adapted to the important case of the body-centred cubic foam. This involves defining two types of cones, corresponding to the two sets of neighbouring bubbles that come into contact. We obtain results which compare favourably with accurate computations using the Surface Evolver. The precise dependence of energy on liquid fraction close to the loss of the < 100 > contacts remains to be resolved.
