线性谐振子的坐标-动量不确定关系

The Uncertainty Relation of Linear Oscillator

讨论了量子力学中的不确定性原理,定量计算了线性谐振子的坐标-动量之间以及动能-势能之间的不确定度,证明了它们满足一般的不确定关系,并澄清了一些有关不确定关系的错误理解和描述.

Using the uncertainty principle of quantum mechanics,in the system of one-dimensional linear oscillator, position and momentum uncertainties and kinetic energy and potential energy uncertainties are calculated quantitatively. It is shown that they obey the general uncertainty relations. Some misunderstanding and misdescription about the uncertain relations are explained.
