Physical properties that are completely specified by their magnitude are called scalars . 物理性质完全由其大小所确定者叫做标量。
If two vectors are associated with each other as a dot product, the result is a scalar . 如果两个向量以标量积结合,其结果为一标量。
We discuss in more detail the application of the coupled mode formulas to scalar waveguide deformations . 我们将详细讨论耦合模公式对标量波导畸变的应用。
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。
The use of inertia dyadics enables one to deal with certain topics involving inertia vector and inertia scalars in a basis-independent way . 在处理包含惯性矢量和惯性标量的某些问题时,应用惯性张量则可作到与基无关。
