摘　　要：在材料力学教学中,分析截面内力是基础环节。针对控制截面的内力分析,提出一种新方法,即控制截面的极限分析法,对控制截面内力进行分析和理解。在教学实践中,这一方法帮助同学们很好地理解了控制截面处的内力分析问题,更启发同学们运用极限的思想来理解和分析材料力学中的相关内容,是互动启发式教学的一次成功实践。In the teaching of material mechanics, analysis of internal force of section is the basic link. Towards internal force analysis for the control section, a new method, named limit analysis method of the control section, is proposed to analyze and understand the internal forces of the control sections. In teaching practice, this approach helps students understand the problem of analyzing the internal forces of the control section, and inspires students to use the idea of the limit to understand and analyze mechanics of materials-related content. As a teaching tool, it is not only the combination of the disciplines, but also innovation of the interactive heuristic teaching method.
