The definition of work suggests a third process of vector algebra, namely, scalar multiplication of two vectors . 功的定义用到矢量代数的第三种运算，即两个矢量的标积。
Since scalars are independent of the coordinate system, the dot product of two vectors is called a scalar invariant . 因为标量与坐标系无关，故两个矢量的点积称为标量不变量。
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。
As the vectors go around, the amplitude of the sum vector gets bigger, and smaller, and the intensity pulsates . 在矢量旋转时，合矢量的振幅时而变大，时而变小，因而强度作脉动变化。
One significance of the eigenvectors is seen to be that they determine the values of the state variables in a characteristic mode . 本征矢量的重要意义之一是，它们决定了在一定模态中状态变量的相对值。
The dot product of two vectors is defined as follows 两个矢量的点积定义如下：
