在轻松滑行开始时测量了锗晶体的六个二级滑行系统的潜在硬化。在交叉系统的情况下，可以通过在单滑移的流动应力中添加森林相互作用项来解释结果。该项相当于 (aGb √N f )，对于各种类型的位错切削，a 为 0.35，对于交叉滑移系统，a = 0.64。 （G 是适当的剪切模量，b 是伯格斯矢量的长度，N f 是森林位错的密度）。鲍辛格效应似乎证实了法伯和尤宁检测到的位错迁移率的各向异性。
The latent hardening of six secondary glide systems of germanium crystals has been measured at the begin of easy glide. The results can be explained in case of intersecting systems by adding a term for forest interaction to the flow stress of single slip. This term amounts to (aGb √N f ) with a 0.35 for various types of dislocation cutting, and a = 0.64 for the cross glide system. (G being the appropriate shear modulus, b the length of the Burgers vector and N f the density of forest dislocations). The Bauschinger effect seems to confirm the anisotropy of dislocation mobility detected by Farber and Iunin.
