中文摘要：

微观粒子的波粒二象性导致了许多日常经验不能理解的一些现象,初学者会有很多困难和困惑.可是电子、原子等微观粒子无法被直接看到,对于初学者来说比较抽象,其量子效应难以理解.在教学中,为了突出量子理论与经典理论的矛盾,可将量子效应放大到宏观物体,让学生更直观、更形象地感受到奇特的量子现象对日常经验的冲击,从而加深对基本概念的理解.本文列举了几个例子,通过改变普朗克常量将宏观物体的量子效应放大,得到有趣的结论.

英文摘要：

The wave-particle duality of micro particles could lead to many effects that are hard to be understood by daily experiences, thus beginners have many difficulties and easily fall into confusion in learning the basic concepts of the quantum physics. The quantum effects are too abstract to be understood for a beginner because the electrons and atoms in microphysics can not be seen directly and hard to imagine. In teaching atomic physics and quantum physics, one can magnify the quantum effects to the macro world to show the strong conflicts between the peculiar quantum effects and people＇ s daily experiences. In this paper some examples are introduced to show this technique, which will be helpful in understanding the basic concepts. The quantum effects are magnified to the macro objects by artificially change the Planck constant,and therefore lead to some interesting results.
