摘要：

We have examined experimental and simulation data on the relaxation times (tau(alpha)) and the viscosities in liquids and supercooled liquids as functions of temperature (T), density (rho), and pressure (p). We achieve a data collapse by placing the data on master curves that depend only on a single density- and species-dependent (but T independent) effective interaction energy, E-infinity(rho).
