摘　　要：通常人们认为电磁矢势A的环量才有物理意义,而每点上的A值是没有直接的物理意义。本文从场的能量、动量角度;从量子力学水平上通过实验对A进行直接观测的角度,提出A应该是具有物理意义的物理量。It is generally believed that only circuit value of electro-magnet vec tor-potential A has physics meaning while value A on each point does not.From t he perspective of energy and momentum of field,through direct observance of expe riments on the basis of quantum mechanics, the writer of this article proposes t hat A should be a quantum with physics meaning.

关 键 词：电磁矢势 物理意义 A^→ 磁场
