摘要
利用Levi—Civita张量及其基本性质，讨论了量子力学中坐标、动量及角动量的对易关系，给出了相关习题的一般解法．该解法可帮助学生克服在量子力学学习中解此类习题的困难．
In the paper, the authors discuss the commutation relations of coordinates, momentum and angular momentum operators by using the Levi-Civita tensor and its basic properties. The general methods for the solution of this kind of exercises are given out. The methods are helpful to those students to overcome their problems in studying quantum mechanics.
