在相网络渗流模型的基础上，讨论了橡胶共混物中相形态和炭黑分布对玻璃化过渡区粘弹性的影响。结果表明，在某些相为玻璃态而另一些相为玻璃态的温度范围内，局部硬度的较大差异不会导致本征局部应变与外部应变幅值的显著偏差。基于这些考虑，提出了一种程序，允许从力学-动力学数据对相中的炭黑浓度进行定量估计
The influence of phase morphology and carbon black distribution in rubber blends on viscoelastic properties in the glass transition regime is discussed on the basis of a percolation model for the phase network. It is shown that large differences in the local hardness of the phases in the temperature range where some phases are glassy but others do not lead to significant deviations of the intrinsic local strain from the external strain amplitude. Founded on these considerations a procedure is represented that allows for a quantitative estimation of carbon black concentration in the phases from mechanic-dynamical data
