这种相对的脆弱第一是由于静电斥力比较小第二是由于吉布斯-马朗戈尼机制很容易被打乱。

That relative fragility arises both because the electrostatic repulsion is small and because the gibbs-marangoni mechanism is easily disrupted.

因此，啤酒泡沫的稳定性来源于一种很强的吉布斯-马朗戈尼效应，这种效应在吸附的蛋白质可以有效改变表面张力时是最优化的。

Beer foam stability is thus promoted by a strong gibbs-marangoni effect, which is optimized when absorbed proteins are efficient at changing the surface tension.
