0 something that has size but no direction, such as a quantity, distance, speed, or temperature -- 标量的（只有大小没有方向的，如数量、距离、速度或温度）
In the sections on the analysis of subdivision schemes, we consider only schemes with scalar masks.
Since the scalar potentials are matched at the reference surface, it follows that they are matched globally.
Regularization of the stress-energy tensor for vector and scalar particles propagating in a general background metric.
This motivates scalar construal which systematically limits the licensing potential of polarity triggers.
But perhaps this claim is more controversial on the scalar than on the bivalent view.
The results apply to semi- and fully discrete approximations of scalar and systems of conservation laws.
Reversing any of these conventions on orientation may change local signs in the incidence function, but not the final, scalar results of computations.
The inner product of two vectors is equivalent to the standard scalar (dot) product.
