摘　　要：A-B效应中显示屏上某一点的相位差决定于闭合路径所围平面的磁通量,是一个规范不变的物理量.在此基础上,可以定义某一条开路路径的电子波函数的相位,进一步,定义任意开路的电子波函数的相位,由此可以解决A-B效应中开路波函数相位因子中规范变换所导致的不确定性,进而揭示A-B效应的本质,可以用来计算量子现象中的不可积相因子,于量子几何计算方面亦有一定的助益.The phase difference of a point on the viewing screen in the A-B effect is depended on the magnetic flux in the plane of the closed path,which is a gauge-invariant physical quantity.This paper indicates on this basis that the phase position of the electron wave function in an open-circuit path can be defined by the phase difference.Furthermore,the phase position of the electron wave function in random open-circuit path is defined so as to settle down the indeterminacy resulted from the gauge transformation of open-circuit wave function phase position in A-B effect.The results reveal the nature of the A-B effect,which is contributed to the calculation of the non-integrable phase factor in the quantum phenomenon and the quantum geometry calculation.
