标题： Comments on the Quantum Vacuum and the Light Acceleration

摘要： 最近对类星体吸收线光谱的观测以及这些线与实验室光谱的比较，为通过考虑精细结构常数在宇宙时间尺度上的变化来解释这些观测提供了一个框架。 此外，似乎先驱者号航天器10/11存在异常加速，约为$ 10^{-10} {\rm m}/{\rm s^2}$。 这些情况促使Ranada研究量子真空，通过引入一个现象学模型来解释这些问题，以说明$\alpha$的变化。 在本文中，我们想表明该模型不是一个量子模型；它是一个经典模型，仅通过调整一些参数与上述观测一致，并非基于基本的物理直觉。 显示英文摘要

摘要： The recent observations on the far quasars absorption lines spectra and comparison of these lines with laboratory ones provide a framework for explantation of these observations by considering a varying fine structure constant, over the cosmological time-scale. Also, there seems to be an anomalous acceleration in the Pioneer spacecraft 10/11 about $ 10^{-10} {\rm m}/{\rm s^2}$. These matters lead Ranada to study the quantum vacuum to explain these problems by introducing a phenomenological model for the variation of $\alpha$. In this manuscript we want to show that this model is not a quantum model; it is a classical model that is only in accordance with mentioned observations by adjusting some parameters and is not based on a fundamental physical intuition.
