摘要：

Molecular dynamics simulations for undercooled glass-forming Ni0.5Zr0.5 liquids are analyzed to evaluate the memory kernel that governs the decay of structural fluctuations according to the schematic model of the mode coupling theory. The resulting kernel exhibits significant structures which explains the absence of the inverse power law decay in the early beta regime.
