不确定关系的简明推导与正确理解

Simple Deduction and Correct Understanding of Uncertainty Relation

根据德布罗意波假设,采用无限深势阱模型,利用驻波条件,求出无限深势阱中微观粒子的动量分布。根据不确定度的定义,计算无限深势阱中微观粒子的位置和动量的不确定度,导出无限深势阱模型的不确定关系。对不确定关系正确理解进行了讨论。

According to de Broglie wave hypothesis, based on one dimensional infinite wall and by using standing wave condition, distribution of momentum of a particle in one dimensional infinite wall is deduced. With reference to the definition of uncertainty, position uncertainty and momentum uncertainty are calculated and uncertainty relation of one dimensional infinite wall is deduced. Correct understanding uncertainty relation is discussed.
