摘要
根据经典狭义相对论，任何以速度v运动的非平稳系统的演化(例如，衰变)必须比静止系统慢1/ 1倍，= (1 v 2) 1/2(爱因斯坦延迟ER)。量子力学允许人们分别计算两个系统的演化，并对它们进行比较，从而验证ER。本文表明，对于一个简单的系统，即自由无自旋粒子的扩散包，ER是不成立的。前面已经表明，ER不适用于其他一些系统。所以有人可能会说，ER不是量子力学中普遍的运动定律。
According to the classical special theory of relativity any nonstationary system moving with velocityv must evolve (e.g., decay) 1/ times slower than the system at rest, = (1 v 2 ) 1/2 (the Einstein retardation ER). Quantum mechanics allows one to calculate the evolution of both systems separately and to compare them thus verifying ER. It is shown here that ER is not valid for a simple system: the spreading packet of the free spinless particle. Earlier it was shown that ER does not hold for some other systems. So one may state that ER is not a universal kinematic law in quantum mechanics.
