标量电位
电标量势

Secondly , some recently research results and some unsolved problems about the magnetic vector potential a , electric scalar potential and magnetic scalar potential of the transient eddy current formulation are deeply analyzed in the paper and the magnetic vector potential a is chosen to calculate the specified physical model discussed in this paper
其次，概括地分析了国内外对向量磁位( ? ) 、标量电位、标量磁位的研究现状及存在的问题，在此基础上，确定用向量磁位( ? )来计算永磁操动机构的物理模型，并证明在二维非线性情况下，库仑规范自然满足。
