摘要
量子力学中力学量和表象理论无论在教学中还是在实际应用中都占有非常重要的地位,是量子力学的重要内容,也是教学的重点和难点.文章提出了力学量和表象理论的“五步”计算方法,分别对应为“找、解、展、求、算(写)”.通过教学实践和实例应用发现,它能很好地解决力学量和表象理论一系列的计算问题,帮助学生掌握量子力学的内容和知识体系,对提高量子力学教学产生了积极的影响.
In quantum mechanics,mechanical quantity and representation theory play a very important role in both teaching and practical application.They are not only an important content in quantum mechanics,but also a key and difficult point in teaching.This paper puts forward the"five step"calculation method of mechanical quantity and representation theory,which corresponds to"find,solve,develop,seek and calculate(write)"respectively.By teaching practice and example application,it is found that it can well solve a series of calculation problems of mechanical quantity and representation theory,help students master the content and knowledge system of quantum mechanics,and have a positive impact on improving the teaching of quantum mechanics.
