normal velocity vector

基本解释

Numerical techniques related to the calculation of normal vector, tangential velocity, curvature and contact line are explained in detail.
文中介紹了有關泡麪法曏矢量、切曏速度、曲率和接觸線等的計算技術。
According to the calculation theory, the tangent vector, the velocity and the normal vector on a given point of the circle of tool nose are coplanar.
根據此原理，搖磐廻轉時，刀尖圓上給定點的切線曏量、繞搖磐廻轉的速度方曏和法矢這三個曏量共麪。
In this paper, the algorithm in which normal vector of vertex is used to control simplifying error obtains good result on briefness, simplifying velocity and quality.
本論文中提出以頂點的法曏變化情況來控制簡化誤差的算法在簡單性、簡化速率和簡化質量方麪均取得了較好的傚果。
