论文摘要
Small (compared to coherence length) weak superconducting defects when located at the surface, combined with the proximity and percolation effects, are claimed responsible for various observations with superconducting rf accelerating cavities with non-constant Q-value, such as "Q-slope" and "Q-drop", the role of temperature, the result of "nitrogen doping" and its relation to the free path, and the静态外部磁场的影响。 Ginzburg-Landau方程用于确认结果。

The Ginzburg-Landau equations are used to confirm the results.
