第二类超导体中磁通钉扎的表达式是从考虑单个磁通线和钉扎中心之间相互作用的性质以及钉扎中心的几何形状导出的。它表明，实验观察到的标度律得到的必要性，而无需引入磁通晶格弹性的概念。预测的钉扎功能被发现提供足够的解释测量洛伦兹力曲线在很宽的范围内的高K，强钉扎材料。
Expressions for flux-pinning in type II superconductors are derived from considerations of the nature of the interaction between individual flux-lines and pinning-centres, and of the geometry of the pinning-centres. It is demonstrated that the experimentally observed scaling laws are obtained without the necessity of introducing the concept of flux-lattice elasticity. Predicted pinning functions are found to provide adequate explanation of measured Lorentz force curves in a wide range of high-K, strong-pinning materials.
