一般文献对A—B效应的分析不够明了，作者就此问题进行了探究，力求寻求一种既省时又省力简单明了的方法，试着用费曼的的路径积分理论定量地分析由矢势A和标∞势所致的A_B效应及超导量子干涉效应、介观体系中的A_B效应等这些前沿领域的课题。-general literature on A-B and analysis of the effect of not sufficiently clear, the authors conducted on the issue inquiring, strive to find a save time and straightforward way, tried using the Feynman path integral theory of quantitative analysis by the vector potential A - infinity and the situation caused by A_B superconducting quantum effects and dry involved effect mesoscopic system of A_B effects such as frontier areas of the subject.
