本文前言中开发的方法用于查找两个结晶固体界面上堆积的 n 个螺旋位错的位置。堆积是由恒定的施加应力引起的，当 n → 无穷大时，位错的定位足够准确，可以预测界面处大但有限的应力分布。使用传统的连续位错密度不可能进行这样的预测。
The methodology developed in the precursor to this paper is used to find the positions of n screw dislocations in a pile-up against an interface bonding two crystalline solids. The pile-up is caused by a constant applied stress and, as n →∞, the dislocations are located with sufficient accuracy to predict the large but finite stress distribution at the interface. Such a prediction is impossible using a conventional continuum dislocation density.
