计算了第二类超导体中小缺陷在上临界磁场附近的元钉扎势。该计算适用于所有温度和金属的所有背景杂质含量。发现当加入其它杂质时，钉扎势随杂质参数的倒数而衰减。在Ginzburg-Landau区得到了一个非常简单的钉扎势公式。在小缺陷的Ginzburg-Landau理论的边界条件。
The elementary pinning potential of a small defect in a type II superconductor is calculated near the upper critical magnetic field. The calculation applies at all temperatures and all background impurity contents of the metal. The pinning potential is found to decay according to the inverse impurity parameter when other impurities are added. A very simple formula for the pinning potential is obtained in the Ginzburg-Landau region. The boundary condition to be imposed on a Ginzburg-Landau theory at small defects is derived.
