摘要：

A molecular dynamics simulation of (Li,K)SiO3 has been carried out to determine the mixed alkali effect. A decrease in dynamic property by mixing is reproduced by the simulation. The distinct part of the van Hove function reveals that the jump of alkali ions into a site previously occupied by a different type of alkali ion has a low probability in a mixed alkali glass. The result means that an interception of the mutual diffusion pathways occurs in the glassy state.
