本文报道了一类超导体中钉钉力Fp与晶粒尺寸D之间的关系，该关系是基于流体与形成晶界壁的位错的相互作用而得出的。在近似证实了实验观测到的Fp∝1/D关系的同时，理论预测了Fp在a0/D处的峰值，其中a0是通量线晶格的晶格常数。
A relationship between pinning force Fp and grain size D in type‐II superconductors derived on the basis of interaction of fluxoids with dislocations forming the grain‐boundary walls is reported. While confirming approximately the experimentally observed Fp∝1/D relationship, the theory predicts a peak in Fp at a0/D≃0.2, where a0 is the lattice constant of the flux line lattice.
