考虑不可压缩粘弹性材料的乳液，其中加入界面剂导致界面张力依赖于剪切变形和面积的变化。介质的平均复剪切模量通过类似于电学中的洛伦兹球方法的自洽处理来解释夹杂物之间的机械相互作用。由此产生的平均模量的表达式包括作为特殊情况的Kerner公式的不可压缩的弹性材料和Oldroyd表达式的复杂粘度的乳液的牛顿液体随时间变化的流动。
Emulsions of incompressible viscoelastic materials are considered, in which the addition of an interfacial agent causes the interfacial tension to depend on shear deformation and variation of area. The average complex shear modulus of the medium accounts for the mechanical interactions between inclusions by a self consistent treatment similar to the Lorentz sphere method in electricity. The resulting expression of the average modulus includes as special cases the Kerner formula for incompressible elastic materials and the Oldroyd expression of the complex viscosity of emulsions of Newtonian liquids in time-dependent flow.
