摘要：

In this Letter we study the behavior, versus temperature, of tracer diffusion in random materials, for example, amorphous solids. By using a combined approach, using the analytical continuous-time random-walk theory and Monte Carlo simulations, we are able to propose a possible explanation for the nearly Arrhenian behavior observed in most amorphous solids by a compensation between site and saddle disorder. © 1990 The American Physical Society.
