摘要

对角量矢量性的讨论,或通过图形比较,或通过公式计算,都得出了无限小转动是矢量、有限转动不是矢量的结论,但都不曾指出根本的物理原因.通过物理量的不变性和变换的协变性,证明了转动矢量不是真矢量,并且得出其本质原因是坐标系的左旋和右旋.

Abstract

Discussion on vector properties of angular physical quantity,through graphic

comparison,or through formula calculation,many papers draw the conclusion that infinitesimal

rotation is vector and finite rotation is not vector.Neither point out the physical

fundamental reason. According to the invariance of physical quantity and the covariance of

transformation,it is proved that the rotation vector is not true vector,that of the essential

reason is the levorotation and dextrorotation of the coordinate system.

Key words: vector; tensor; inversion; parity
