论文摘要
我们研究流体界面的表面张力对第三悬浮相的密度曲线的依赖性。通过二进制混合物的近似模型和扰动方法，我们得出了系统的自由能和界面表面张力的密切公式。我们的结果表明，表面张力在悬浮相密度的峰值上具有显着的非单调依赖性。我们的结果还可以预测表面张力的局部值，在悬浮相的密度沿界面不均匀的情况下。
We study the dependence of the surface tension of a fluid interface on the density profile of a third suspended phase. By means of an approximated model for the binary mixture and of a perturbative approach we derive close formulas for the free energy of the system and for the surface tension of the interface. Our results show a remarkable non-monotonous dependence of the surface tension on the peak of the density of the suspended phase. Our results also predict the local value of the surface tension in the case in which the density of the suspended phase is not homogeneous along the interface.
