摘　　要：通过比较电磁学教学中所讲到的德鲁特的金属经典电子论与超导体的伦敦方程,作者指出,同样的方法,不同的对象,不同的唯象模型,得出了截然不同的结论;说明由宏观进入微观,由现象到本质,物理学一般都经历唯象理论;提出在教学中如何适当介绍前沿进展是引人瞩目的课题,伦敦方程提供了一个范例.By comparing Drude classical electron theory of metal with London equation of superconductor those are taught in electromagnetism, author indicates that by use of the same method and different phenomenological model for different objects completely different conclusions have been obtained; from macroscopic domain to microscopic domain phenomenon to essence the developing of physics generally passes through phenomenological theory; how properly to introduce the knowledge of the frontier and progress in science to students is a task which is the focus of people attention, however London equation is the best template.
