研究了自由三维量子力学波包的扩展或收缩，并提出了一些结果。讨论了关于时间演化算子和非扩展波包的看似悖论，并强调了考虑量子力学适当数学结构的必要性。给出了对量子力学教学的启示。
The spreading or shrinking of free three‐dimensional quantum‐mechanical wave packets is studied, and several results are presented. A seeming paradox concerning the time evolution operator and nonspreading wave packets is discussed, and the necessity of taking into account the appropriate mathematical structure of quantum mechanics is emphasized. Implications for the teaching of quantum mechanics are given.
