relative slip meaning in English

相对滑动

By means of a detailed analysis to the interaction between droplet and its carrying fluid for horizontal stratified / atomization two - phase flow , a theoretical model is proposed to calculate the droplet axial velocity profile and the relative slip between dispersed phase and continuous phase
摘要通过对水平分层雾化流中液滴和其携带流体间交互作用的分析，提出了一个预则水平分层雾化流中轴向液滴速度分布以及弥散相和连续相之间相对滑移的理论模型，通过计算获得了两相速度参数及相对滑移参数。
Based on the assumed vertical displacement of the unit cell and the assumed distribution on the pile - soil interface of the pure friction pile , and using the boundary conditions that there was no relative slipping between pile and soil , the pile decrement was equal to that of soil on the pile - soil interface and that the vertical sheer stress of the unit cell ' s outer edge was equal to zero , the formula for the frictional distribution of the pure friction pile and the formulas for the displacement of pile and soil in the treated area were deduced
通过假定的单元体竖向位移模式和纯摩擦桩桩侧摩阻力分布模式，利用桩土间无相对滑移、桩土界面处桩土压缩量相等和单元体边界处竖向切应力为零等边界条件，推导出复合地基纯摩擦桩桩侧摩阻力分布的具体表达式，以及加固区桩土压缩量的计算公式。
