摩擦项 meaning in Chinese
friction term
Examples
- The study shows that the longitudinal component of the pressure force is mainly balanced by the vertical eddy frictional term and the lateral component of the pressure force is mainly balanced by the coriolis force
研究表明：在磨刀门河口动力平衡中，纵向的主要平衡项为压力项和垂向涡动摩擦项，侧向的主要平衡项为侧向正压力项和科氏力项。 - ( 2 ) increasing of wind is mainly induced by shf and affecting of lhf is very little . ( 3 ) effect of terrain increases ground rough and tonsure of terrain press and fiction correspond enhance frictional damp effect
( 3 )地形作用相当于增加了地面粗糙度，地形压力梯度项与摩擦项地叠加，相当于使摩擦阻尼作用增大，地形强迫作用使下边界层从上至下风速减小，风向向左偏转。 - In order to know the relationship between gas - content and pipeline ' s pressure drop , the thesis deduces the pressure drop calculating equations based on uniform flow pattern and separating flow pattern . the equations show that pressure drop is made up of three parts , that is , friction resistance effect , gas acceleration effect and the gravity effect . and the research has shown that the gas has little effect on pressure drop . in the horizontal pipeline , the resistance effect must be overmatched the acceleration effect
为探讨加入的气体对管道压力的影响，本文基于分相流和均相流两种模型分别推导了三相流管道的压降公式，表明无论是分相流模型，还是均匀流模型，管道内流体总的压降是由三项组成的，即摩擦项、加速项和重力项，并得出了加气对管压变化不大的结论，所以认为在水平管道中，要获得有效的减阻，则要使摩擦阻力分量的减小效应大于浆体加气的加速效应。
