我们使用X射线层析成像来表征平均液体分数φ（1）近似为17%的液体泡沫中所有气泡的几何形状，并跟踪它们的演变，测量7000个气泡的归一化生长速率G = V-1/3dV/dt。虽然G不仅取决于气泡的面的数量，但其在f面气泡上的平均值在任何时候都以G（f）的形式缩放，类似于f - f（0）。讨论了G的色散以及V和φ（1）对G的影响。
We used x-ray tomography to characterize the geometry of all bubbles in a liquid foam of average liquid fraction phi(1) approximate to 17% and to follow their evolution, measuring the normalized growth rate G = V-1/3dV/dt for 7000 bubbles. While G does not depend only on the number of faces of a bubble, its average over f-faced bubbles scales as G(f) similar to f - f(0) for large f's at all times. We discuss the dispersion of G and the influence of V and phi(1) on G.
