摘要：

The coherent density correlation function, PHI-(Q, t), in a supercooled one-component simple liquid approaching liquid-glass transition was simulated using the molecular dynamics system comprised of 16384 particles. A new pair potential used in this study was constructed to avoid crystal nucleation. The shape of the corresponding dynamical susceptibility spectra chi"(Q, omega) in the alpha- and beta-relaxation frequency ranges has been analyzed, and its wavevector dependence was found to be in good agreement with that predicted by the mode-coupling theory.
