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）
With scalar-variable application defined, we can lift the application of a substitution to general types with no difficulty.
This would reduce the problem once more to determining sequences of scalars and, if one chooses well, their number need not be prohibitively large.
Only 22 of the set of 30 scalar equations derived from (28) are independent.
The scalar potential in the continuity and momentum equations is taken as the linear combination of the electrostatic and self-gravitational potential.
The scalar organisation of these chorus melodies also offers an interesting contrast with their verses.
The other operations involve vector-vector dot products, scalar-vector multiplies, and in general, only operations involving vectors.
The operands considered mostly in engineering design include scalars and three-dimensional vectors.
The inner product of two vectors is equivalent to the standard scalar (dot) product.
