摘    要:为了更深入地了解相位时间的物理意义,讨论了量子粒子穿越一维方势阱时的反射相位时间计算得出的反射相位时间和透射相位时间数值相等并在一定条件下出现负值现象认为,量子力学中粒子穿越方势阱时,不论粒子最终是被反射或透过势阱,这 过程可只用一个物理量—量子力学中的能速来正确描述

关 键 词:反射相位时间  势阱  能速  渡越时间

Abstract:To understand the physical meaning of phase time further more, we discuss the reflection phase time of quantum-particles passing though a potential well It is shown that the reflection phase time is equal to the transmission phase time in value and negative under certain conditions for a square potential well by analyzing While quantum-particles passing through the potential well, we think that this course can be described only with the velocity of energy of quantum mechanics whether or not they are reflected or transmitted eventually
Keywords:reflection phase time  potential well  velocity of energy  the traversal time
