中文摘要：

液体泡沫是在表面活化剂答案的小数量的煤气的水泡的一件稠密的收拾行李。液体从泡沫排干直到平衡由于在严肃和毛细作用之间的妥协被到达，它极大地影响泡沫的稳定性。在我们以前进行了的泡沫结构和排水上基于一系列工作，原版的结合上的结果强迫了排水的报告与随后的排水以低流动率挥动的这篇论文与更高的流动率飘动。进化粘滞精力和表面精力理论上在结合的过程期间被分析。

英文摘要：

Liquid foam is a dense packing of gas bubbles in a small amount of surfactant solution. Liquid drains out of foams until equilibrium is reached due to the compromise between gravity and capillarity, which greatly affects the stability of foam. Based on a series of work on foam structure and drainage we conducted previously, this paper reports the results on coalescence of an original forced drainage wave at a low flow rate with subsequent drainage waves with higher flow rates. The evolutions of viscous energy and surface energy during the process of coalescence are theoretically analyzed.
