也许我应该用位置矢量来考虑,如果你们觉得有帮助的话。
Or, maybe I should insteadthink of it in terms of a position vector if it helps you.
这还是比较容易想到的，假如这是位置矢量，这是它的变化量。
Well, it might be good to think of, maybe, the position vector, and maybe its variation.
目的探讨位置矢量分析在偏瘫患者平衡功能评定中的应用。
Objective to investigate the application of position vector in balance evaluation of stroke patients with hemiplegia.
如果你看一下任何时刻运动时的，位置矢量和速度矢量，它们决定了某个平面。
So, if you just look at the position vector, and the velocity vector for any motion at any given time, then together, they determine some plane.
你可以说，位置矢量在另一个时间或在任何时间，无论如何，位置矢量始终在这个平面上。
You could say the position vector at another time, or at any time, but in fact, what's also true is that the velocity vector is in the plane.
后者首先同步车速矢量与北斗卫星测量得到的车辆位置矢量，再根据融合结果估算车辆定位信息。
The latter estimates the vehicle position by synchronizing the speed vector and the position vector measured by Beidou system.
