The cleavage and schistosity acted as an axial plane role in the early generation of compressed shear fold, and changed into a slip plane in the later generation of flexural slip fold.

片理（劈理）为早世代挤压-剪切褶皱的轴面片理，又成为晚世代弯滑褶皱的滑动面；

Moreover, the influences of slip for deflection, elastic flexural capacity and ultimate flexural strength are researched, and corresponding formulas are inferred.

在此基础上研究了滑移对组合梁挠度、弹性抗弯强度及极限抗弯强度的影响，并建立起相应的计算公式。

The bond and slip relationship between the rebar and the concrete within a segment bounded by two primary cracks in a reinforced concrete tension member or a flexural member is studied.

本文主要研究钢筋混凝土轴心受拉和受弯等构件中两根主生裂缝之间的钢筋与混凝土的结合(过去常称为粘结或握裹)与滑移关系。
