Now, another useful notion is the unit vector to the trajectory.
还有一个有用的概念就是轨道的单位矢量。
OK, so if I give you a unit vector, you can ask yourself, if I move in the direction, how quickly will my function change?
也就是，如果我给你一个单位向量，试问，我沿着这个方向移动，我的函数值会变化得多快呢？
This article presents the unit vector method for the full shaking force balancing of multi-loop spatial linkages.
本文提出了多环空间连杆机构摆动力完全平衡的单位向量法。
The terminal sliding mode controller is designed by using unit vector style, and it suits the uncertain elements whether it satisfies the matching condition or not.
采用单位向量控制形式的最终滑动模态控制器，对满足匹配条件和不满足匹配条件的不确定性均适用。
