【Abstract】 By means of the comparing electric fields with gravitational fields, we can find that the concepts for the description of the fields correspond to each other, the research methods are same, and the physical laws are connected with each other. The comparative teaching helps students grasp the properties and laws of electric fields, learn the description of the fields and the method of research on the fields. As a result, it lays a solid foundation for the students for their futrue study.更多还原
