摘要
文章对量子力学中单个力学量在本征态和非本征态中有无确定值和多个力学量同时有无确定值的条件进行讨论。说明单个力学量处于本征态时有确定值,多个力学量算符对易时力学量同时有确定值,而在非本征态中无唯一确定值。
This article dicusses whether single mechanical quantity has certain value in eigen state and uneigen state and discusses the conditions for several mechanical quantities to have certain values simultaneously in the quantum mechanics
