摘要
采用与通常教科书不同的方式,讨论了量子力学中的一些对初学者很难理解的概念,如量子化、对易关系、用矩阵表示力学量、引进复数i等.解决在实轴上“挖洞”、映射到实数以及找出作为动力学变量的生成元,都是与对上述概念的理解相联系的.
In Quantum Mechanics, many concepts such as quantization, commutation relations, representation of mechnanical quantities by matrices and introducing the complex number i are difficult to understand for the students studing quantum mechanics for the first time. These concepts are discussed in present paper using different way from normal teaching books. Solving the 'gaping-holes' problem, mapping to real numbers and finding generators as dynamical variable are related with understanding above concepts.
