摘要
根据时谐形式的麦克斯韦方程组，导出了均匀媒质中修正矢量磁位Ａ￣＊的散度表达式。在此基础上，建立了非齐次亥姆霍兹方程的Ａ￣＊边值问题，并证明了Ａ￣＊解答的唯一性，最后以有显式解的涡流场为例验证了本文建立的边值问题的正确性。
The divergence expression of modified magnetic, vector potential A in homogeneous media was obtained from the time harmonic Maxwell's equations . From this, a boundary value problem of nonho- mogeneous vector Helmholtz's equation representative by A was established . The uniqueness of solu- tions of the problem was also proved . Finally, the provided formulas were tested and verified by an eddy current field with explicit solution.
