粒子穿越势阱及光子穿过薄玻璃板时的能速及渡越时间

采用一与电磁波场中能速概念含义相似的物理速度－能量运动速度（简称能速）来描述量子力学中粒子穿越势阱过程，此能速对应的粒子渡越时间和相位时间相比，不存在负值现象。此能速同样可以用来描述光学中光子穿过非色散薄玻璃板介质时的过程，和相应的相位时间相比，此能速对应的光子渡越时间也不存在负值现象。给出了实验上测量光子渡越时间的方法。

The Velocities of Energy and Traversing Times of Particles Passing Through A Potential Well and Photons Travelling Through A Thin Glass Plate

A physically meaningful speed - the velocity of energy is used, which is similar to the energy speed in electromagnetism, to describe the process of particles passing through a potential well. It is shown that the corresponding traversing time of particles isn' t negative as the phase time, which is negative under certain conditions. This speed can also describe the process of photons travelling through a non - dispersing thin glass plate. The corresponding traversing time of photons isn' t negative as the phase time either. We provide an experimental method to test and verify the proposed traversing time.
