vector sum
常见例句
- In so far as linear motion is concerned, a body is in equilibrium if the vector sum of the forces acting upon it is zero.
就线性运动而论,如果作用于严格物体上的诸力的矢量之和是零,那么这个物体就处于平衡状态。 - The change in the momentum of a system of particles during an impact is equal to the vector sum of all the external impulses acting on the system.
碰撞时质点系动量的改变等于作用在质点系上所有外碰撞冲量的矢量和。

而其实体的总的虚拟交互力是在FV和EE两种基本接触模式下所分割的所有立方体间的矢量和。 - It is clear that that vector is the sum of that vector and that vector, by the rules of vector addition, because that plus that is equal to the A.
这个矢量是这个两个矢量之和,根据矢量加法的法则,因为这两个矢量相加就等于 A
