摘要：

We show a nonlinear materials equation of superconductors in the form of an extended power law which can be derived from the Ginzburg-Landau (GL) functional. The critical current J(c) and ac susceptibility chi are analysed by using this equation, and the puzzling question of the increasing height of the out-of-phase susceptibility peak chi''(peak) with increasing amplitude h(ac) is explained.
