在物理教科书中,存在着许多语言精炼、含意深刻的物理语句.表面上看似平常,每个学生都能说上几句,但不涉及到灵活应用,多数学生就显得无能为力了.因此,教学中(特别是复习教学)有必要把这些分散在各章节中的典型物理语句集中“扫描”,强化应用. In physics textbooks, there are many linguistic refinements and profound physical statements. On the surface, it seems ordinary, every student can say a few words, but it does not involve the flexible application, most students seem to be powerless. Therefore, teaching In the middle (especially reviewing teaching) it is necessary to “scan” these typical physical statements scattered in each chapter to strengthen the application.
