本文介绍理论力学教研室因陋就简制作的几件教学实验模型。实践证明,用直观的形象方法,配合必要的实验,对提高教学质量颇有好处;尤其有利于改变理论力学课教学中自始至终依靠大量数学演示,学生感到抽象吃力的状况。 This article introduces a few teaching experimental models of theoretical mechanics department which are produced simply. Practice has proved that, with an intuitive image method, with the necessary experiments, to improve the quality of teaching is quite good; in particular, is conducive to change the theory of mechanics teaching rely on a large number of mathematical presentations, students feel abstract and difficult situation.
