【摘要】 针对现行大学本科阶段力学课程中能量原理教学前后联系松散、关联性不强的现状,从力学发展及课程侧重两个方面分析了这一现状,最后结合教学实践经验,提出了几门课程间关于加强能量原理教学相关性的几点建议,指出虚功原理的教学是建立能量知识体系的关键。更多还原

【Abstract】 The relationship is loose about energy principle content between courses of mechanics in the current undergraduate teaching.Linkages of previous contents and posterior contents are not strong.The question is analyzed from two aspects.One is the mechanics history;another is that importance of deferent mechanics course is deferent.At last some advices are drawn up to strengthen internal relations of mechanics courses about energy principle content,which is based on penman’s teaching practice experience,and it is pointed out that the key to build knowledge system of energy principle is teaching of virtual work principle.更多还原
