摘　　要：由矢势分析了"三维导体"的自感电动势,利用■=L︳I/t︳给出了"三维导体"无限长同轴电缆的自感系数.直观地说明了自感的成因.The self-induction electromotive force of ＂three- dimensional conductor＂in the light of magnetic vector potential is analyzed. The solution of the self-inductance of ＂three dimensional conductor＂unlimited length coaxial cable is given by using the formula ■=L︳I/t︳,then the cause of formation of the self-conductance is discussed visually.

关 键 词：三维导体 矢势 自感系数
