In a dynamic situation the vector sum of the forces acting on the body vanished as in the static case . 在動力學狀態(tài)下,作用在物體上的力的矢量和與靜力學情形一樣化為零。
In an infinite dimensional space there always exist two subspaces whose vector sum is different from their span . 在一無限空間中恒存在兩個子空間,其矢量和與其張成空間不同。
Any two vectors whose vector sum equals a given vector are called the components of that vector . 假如任意兩個矢量的和等于一個給定的矢量,這兩個矢量就稱為該給定矢量的分量。
As mentioned above, we have not explicitly used the first condition for equilibrium, that the vector sum of the forces be zero . 如上所述,我們沒有直接應用第一平衡條件,即力的矢量和為零。

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 就線性運動而論,如果作用于嚴格物體上的諸力的矢量之和是零,那么這個物體就處于平衡狀態(tài)。
While two ( or more ) electromagnetic waves of the same frequency , same direction of vibration , same phase or constant phase difference superpose in space , the amplitude of composite wave is vector sum of the amplitude of each wave 由兩個(或兩個以上)頻率、振動方向相同、相位相同或相位差恒定的電磁波在空間疊加時,合成波振幅為各個波的振幅的矢量和。
