对于双组分池内核态沸腾，热边界层中生成的汽泡，同时也处于浓度边界层中．本文建立了边界展中汽泡表面张力模型，对温度和浓度引起的表面张力变化进行分析．结果表明，表面张力从汽泡顶部到底部是递增的，从而形成液体沿界面自上而下的Marangoni流．通过汽泡底部微层相界面方程的求解，探讨了微层变形特征，由此分析汽泡脱离机理．微层变形与文献[1]中指出的接触线的变化从本质上是一致的．
For two-component pool kernel boiling, the bubbles generated in the thermal boundary layer are also in the concentration boundary layer. In this paper, the bubble surface tension model in the boundary show was established, and the change of surface tension caused by temperature and concentration was analyzed. The results show that the surface tension is increasing from the top of the bubble to the bottom, forming a Marangoni flow of liquid from top to bottom along the interface. Through the solution of the interface equation of the micro-layer phase at the bottom of the bubble, the deformation characteristics of the micro-layer are discussed, and the mechanism of bubble detachment is analyzed. Micro-deformation and the reference line [1] pointed out that the change of the contact line is essentially the same.
