摘要:
Given the convenience of scaling parameters leading to superimposed or master curves, we study scaling pressures for equilibrium and nonequilibrium properties. By relating those pressures to interparticle forces and pair radial distribution functions, we connect them to the average interparticle distanceR̄.We thus explain the experimental findings of several authors that the scaling pressures pertaining to nonequilibrium situations (stress relaxation, shear viscosity, electrical conductivity of polymers) are larger than those calculated from the pressure‐volume‐temperature relationships.
