摘要：
The frequency dispersion range of the dynamic bulk relaxation modulus K(omega) and shear relaxation modulus A mu(omega) of electrolyte solutions has been determined in relation to the nature of stress tensor damping in the momentum and configuration spaces. Numerical calculations have been carried out for an aqueous NaCl solution in wide frequency, temperature, and density ranges using analytical expressions obtained for K(omega) and A mu(omega) for the exponential-law damping of the fluxes at a certain molecular interaction potential and radial distribution function . It has been demonstrated that the frequency dispersion range of K (r) (v) and A mu(v) for the exponential-law damping of the corresponding fluxes is narrow (similar to 10(2) Hz).
