当有人问到,在大量的现行高等学校电磁学教科书中,有没有一本称得上具有创造性特色的新书呢?我看是有的,《电动力学引论》可以说是这样的一本新书。著者为了创作这本卓有见识的著作,显然付出了艰辛的劳动。 When asked whether there is a new book with a creative character in a large number of existing textbooks for electromagnetism in higher education institutions, I think there is. The introduction of electrodynamics can be said to be such a new book . In order to create this insightful book, the author apparently worked hard.
