摘要
通过分析指出 ,不论是从逻辑学的角度还是从物理学的角度来看 ,将标量定义为只有大小、没有方向的物理量都是值得商榷的 .
It is meaningful to discuss the physical quantity-scalar which is defined to be with size but without direction both from the view of logics and from the view of physics. The exact definition of scalar should be as follows: scalar is a physical quantity expressed by the positive real or the negative real.
