摘要：

The equations built on fractional derivatives describing the anomalously slow diffusion observed in systems with a broad distribution of relaxation times were presented. These systems included charge transport in amorphous semiconductors, spread of contaminants in underground water, relaxation in polymer networks and in arrays of convection rolls. The equations generalized Fick's second law and the Fokker-Planck equation by considering effects such as stretching of polymers under external fields.
