介绍利用Cauchy-Schwarz不等式及厄米算符的性质推证坐标和动量的不确定度关系的方法,并对该不确定度关系进行分析讨论,得到当波函数为高斯函数时,坐标和动量的不确定度关系将取等式形式的结论。
This paper introduces the derivation of position and momentum uncertainty relation from Cauchy-Schwarz inequality and the properties of Hermitian operator, and discusses this uncertainty relation. For a Gaussian wave function, the inequality of uncertainty relation will hold equality sign.
