摘要：

In order to increase the critical current density and trapped magnetic field in high T-c superconducting materials, various kinds of inhomogeneities were introduced and used as pinning centers of flux lines. A universal scaling behavior of the pinning force is observed in different high T-c cuprates. We show that this scaling law isa natural result of a unified materials equation for type-II superconductors. This equation agrees reasonably well with recently observed phenomena.
