量子理论中电磁场矢势的物理图象

Physical features of electromagnetic potential in quantum theory

计算出电磁场矢势Ａ对电子在外磁场中干涉图样位置移动的影响；分析了ＡＢ效应的物理实质；求解了电子在外磁场中的散射问题，给出了散射出现极大和极小值的条件；在量子理论的范围内讨论了关势Ａ的物理意义．

The author has calculated the influence by the electromagnetic vactor potential on interference fringes shifting and analysed the physical nature of AB effect, The scattering problem of electron in out-magnetic field is solved and the conditions are obtained in which the scattering maximum or minimum occurs. The physical meaning of the vactor potential A within the quantum limits is discussed.
