摘要
本文从方向的两个基本要素出发、运用直角坐标转动、反演变换理论，导出物理量有无方向的判据，证明部分标量具有方向，这些标量纯属于双向标量。
In this paper,On the basis of two basic etements of direction,according to the theory of inversion and rotational transform of rectangular Coordinate, judging if physical quantity have direction,proving that some scalar quantitys have direction,and these scalar quantitys are two-way scalar quantity really.
