摘要
本文分析了两类速度定义的实质和物理学中几种速度的不同含义，指出了教学中应注意之处，也有助于加深对波粒二象性的理解．
The essence of the definition of velocities of two classes was analyzed.It has shown that the relationship of the definitions of velocities plays an important role in understanding the wave-particle duality in substance,and we should pay a special attention while teaching.
