摘要：

Viscosity, density, diffusion and self-diffusion data have been collected on the system N-methylpyrrolidone-water at 20 degrees C over the entire composition range. From density and vapour pressure data, affinities, G(alpha beta) (alpha, beta = 1, 2), were computed and compared with the velocity cross-correlation coefficients, f(alpha beta). Good agreement was found between the interpretation of dynamic, f(alpha beta), and thermodynamic, G(alpha beta), data. Both data are in favour of preferential solute-solvent interactions leading to short-lived hydration aggregates.
