摘　　要：对大学物理教材中电位移矢量的定义提出了磋商建议;从动生电动势的产生过程进一步讨论了洛伦兹力的做功问题,对动生电动势的产生机理提出了新观点,洛伦兹力的分力提供了产生动生电动势的非静电力;对空心导体球外表面上的电荷分布做了简单的推导,其目的在于使学生容易理解。The suggestion to give the definition of electric displacement vector in university physical teaching material was proposed. The problem of doing work of Lorentz force was discussed further through the course of producing motional electromotive force. A new view about mechanism of motional electromotive force was presented. The component of Lorentz force provides the non-electrostatic force for producing motional electromotive force. The derivation about charge distribution on the outside surface of hollow conducting sphere was carried out in order to help students to understand easily.
