我们概述了泡沫结构和能量及其对液体体积分数的依赖性的最新进展。我们认为液体泡沫处于平衡状态，其相关能量是表面能。渗透压的测量可用于确定其作为液体分数的函数，与计算机模拟的结果非常一致。这种方法在描述高液体含量的泡沫（即所谓的湿泡沫）时特别有用。对于此类泡沫，X 射线断层扫描被证明是分析有序和无序的重要技术。本文中的大部分讨论也与双液体泡沫（即乳液）和固体泡沫相关，前提是固化保留了最初液体泡沫模板的结构。 (C) 2015 Elsevier B.V. 保留所有权利。
We present an overview of recent advances in the understanding of foam structure and energy and their dependence on liquid volume fraction. We consider liquid foams in equilibrium for which the relevant energy is surface energy. Measurements of osmotic pressure can be used to determine this as a function of liquid fraction in good agreement with results from computer simulations. This approach is particularly useful in the description of foams with high liquid content, so-called wet foams. For such foams X-ray tomography proves to be an important technique in analysing order and disorder. Much of the discussion in this article is also relevant to bi-liquid foams, i.e. emulsions, and to solid foams, provided that the solidification preserves the structure of the initially liquid foam template.
