Beer foam stability is thus promoted by a strong gibbs-marangonieffect, which is optimized when absorbed proteins are efficient at changing the surface tension.
In gas-liquid system, the bigger the resistance ratio of liquid side to gas side is, the more remarkable the enhancement of mass transfer by Marangonieffect becomes.
在气液系统中,液相与气相阻力比越大,由界面湍动引起的传质的增强效应越显著。

As the marangonieffect is easily masked by the presence of a small amount of surface active impurities, it should first be tested whether the experimental gas-liquid system is contaminated or not.
