no-slip

Flow model is established on the basis of slip velocity existing on the wall and inner velocity field in tubes is simulated on the slip wall and no-slip wall and flow characteristics is analyzed.

根据流动在壁面上产生滑移的特点建立了流动模型，模拟了在滑移壁面与无滑移壁面速度场分布的特点，并对流动的相关特性也进行了考察。

It is different from under point contact that there is no stick area under line contact in the partial slip regime, and load distribution within line contact area is uneven due to roughness of surface.

磨痕分析表明，承载区域接触不均匀，存在虚接触区域，其大小与表面粗糙度有关，而接触区域没有不磨损的粘着区，不同于点接触形式。

Makes the transition curve the coordinates of the formula more accurate, more stable performance of the approximate formula, no longer appear before the slip angle constraints and incomplete transition curve calculation of difficult problems.

使得缓和曲线的坐标公式更精确，性能更为稳定的近似公式，不再出现以前偏角限制和不完整缓和曲线计算困难的问题。
