In a dynamic situation the vector sum of the forces acting on the body vanished as in the static case . 在动力学状态下,作用在物体上的力的矢量和与静力学情形一样化为零。
In an infinite dimensional space there always exist two subspaces whose vector sum is different from their span . 在一无限空间中恒存在两个子空间,其矢量和与其张成空间不同。
Any two vectors whose vector sum equals a given vector are called the components of that vector . 假如任意两个矢量的和等于一个给定的矢量,这两个矢量就称为该给定矢量的分量。
