微观粒子动量中的速度

Velocity of Micro-particle in Momentum

在对微观粒子波粒二象性的讨论中涉及到三种速度 :υ粒 、υ相 和υg,它们的含义不同 ,但互相有联系。与微观粒子的波动性相联系的动量 p中的速度应为群速ug (ug=υ粒) ,而不是相速υ相 。若将两者混淆 。

When discussing wave particle duality of micro-particle,we consider three kinds of velocities:particle velocity,phase velocity and group velocity,which are different in meaning but are connected with each other.The velocity in momentum associated with the wave motin of micro-particle is gruop velocity,not phase velocity.Mixing up the two concepts will lead to wrong conclusion.
