论文摘要
DIRAC引入的胸罩和KET符号和维度分析是物理学家的两个强大工具。奇怪的是，关于文献中这两个主题之间的联系几乎什么都没说。我们在这里表明胸罩和样的胸罩具有尺寸。这可以帮助学生更好地理解此抽象符号。
The bra and ket notation introduced by Dirac and the dimensional analysis are two powerful tools for the physicist. Curiously, almost nothing is said about connections between these two topics in the literature. We show here that bras and kets have dimensions. This could help students to grasp a better comprehension of this abstract notation.
