摘要
在现行的某些材料力学教材中,用叠加法求梁变形一节的个别例题,其解题方法并不符合所在教材定义的叠加原理。我们认为,这些例题不利于学生掌握叠加原理,有可能在他们的头脑中形成关于这个原理的模糊概念。鉴于叠加原理是固体力学中比较重要的原理,因此,将此问题提出,以供广大教师及力学工作者探讨。
The solution of some examples about beam deformation calculation in the Section of superposition principle in some current Material Mechanics does not conform with the superposition principle. It is believed that these examples are harful to students' study. Since Superposition Principle is quite important in Solid Mechanics, this paper is published to cause teachers' and mechanics researchers' discussion.
