We recognize this expression as just the scalar product . 可以认出，此表达式正好就是标积。
2.
For this reason the inner product is called also the scalar product . 为此，内积也叫做纯量积。
3.
The scalar product of a vector with itself is the square of the magnitude of the vector . 一个矢量自身相乘的标积等于该矢量大小的平方。
4.
We prefer the form (5.16.7) since it is in conformity with the definition of scalar product in a complex euclidean space . 我们愿意用（5.16.7）这种形式，因为它和复欧几里德空间中标积之定义相谐调。
5.
And we also present a multi - party security scalar product protocol 其中我们还给出了一个安全的多方点积协议。
6.
We prefer the form ( 5 . 16 . 7 ) since it is in conformity with the definition of scalar product in a complex euclidean space 我们愿意用（ 5 . 16 . 7 ）这种形式，因为它和复欧几里德空间中标积之定义相谐调。
