The effect of differential sliding and elastic hysteresis on the frictional force in the rolling linear guide (LG) subjected to preloading is analyzed.
主要分析差动滑动和弹性滞后等因素对承受预加载荷下的滚动直线导轨副摩擦力的影响，得出了过盈量与摩擦力的关系。
The structure of the friction-increasing chain effectively increases the frictional resistance between the wheel and the mud pit so that the anti-sliding effect is good.
该增摩链的结构有效增加了车轮与泥坑之间的摩擦阻 力，防滑效果好。
There existed a "Platform" effect between the frictional force and the load for fine packed OTS self-assembled molecule film.
对于致密有序的自组装分子膜，在摩擦力与载荷间存在“平台”效应。
Therefore, we can reduce the effect of frictional loss in the wellbore by drilling well with larger diameter or producing with small production rate.
因此，可以通过钻较大直径的井眼或控制井以小产量生产来减小井筒压降损失的影响。
When waves act on a vertical cylinder, there are in-line and lift forces. They are caused by the viscous effect, which induces the surface frictional force and flow separation and vortex shedding.
通常将垂直柱体在波浪场中的受力分为正向力(顺流力)与升力，它们是由干粘性流绕钝体产生的摩擦阻力和由于水流绕柱分离产生涡漩而形成柱表面压力分布的不均匀变化而造成的。
