目的 定量分析并解释A-B效应,既势A具有可观测的物理效应.方法 利用费曼的路径积分理论并结合量子理论中动量表象的几率幅对磁矢势A引起的电子几率波相移进行定量分析.结果 尽管电子运动的区域没有任何作用力施加在电子上,却有一额外的相因子附加在电子几率波上,并通过量子干涉显现为干涉条纹的移动,而通过零级极大条纹所移动到的位置,可测量出通电螺线管中的磁通φ.结论 A-B效应不能用局域场B来描述,能够完全恰当的描述磁场的物理量是相因子.

Aim To quantitatively analyze and explain the A-B effect, and potential A has the physical effect which may been observed. Methods Feynman＇s path integral and quantum theory are used to analyze quantitatively phase shift of electron probability wave resulting from the magnetic vector-potential A and then the A-B effect is explained. Results Although the electronic movement goes to region without any action to exert on the electronic, some extra factor attaches actually in the electronic probability wave,and appears the interference fringe move...
