摘要
就稳恒磁场矢势边值关系的一些意见提出质疑,肯定了正统证法的正确性.并从数学角度阐明了物理中碰到的无穷大的性质.此外对矢势切向分量的关系提出了更一般的公式,也给出了所有边值关系的数学本质.
Some viewpoints on boundary conditions of magnetic vector potential are criticized, and the conven- tional methods are justified. The properties of infinity in physics are clarified form the mathematical viewpoint. Mo- reover, a more general boundary condition for tangent components of vector potential is proposed, and the mathe- matical essence of all boundary conditions is given.
