| 摘 要： | 论证了在量子力学中,描写系统状态的态矢即即概率幅的概念是最根本的概念,它比描写动力学变量的算符的对易关系等性质更为重要。还举出了一般教材中常见的几个问题做例子来说明这一点。

| Abstract: | In quantum mechanics, the state vector describing the physical system is the primary concept rather than the commutator of operators describing various observables. Arguments concerning this problem and discussions to a few relevant examples in current textbooks are given. |
