论文摘要
相对论的特殊理论告诉我们，尽管独特的惯性框架认为相同的动态定律，时空间隔的价值不同。我们使用快速移动的实验室的范式模型来重新审视时间收缩问题，在该模型中发出光子并向后吸收。但是，在我们的模型中，实验室由两个独立的平行板组成，每个平板都可以充分光线，以便在发射和吸收光线时获得回扣。我们表明，实验室的轻度突显了时间收缩。我们还讨论了光子移动镜中反射时的光子频率如何变化。尽管通常无法察觉，但每当涉及实际的有限质量物体时，这些影响将不可避免地存在。从根本上讲，他们应该必然渗透到相对论量子框架问题的任何最终方法。
The special theory of relativity teaches us that, although distinct inertial frames perceive the same dynamical laws, space and time intervals differ in value. We revisit the problem of time contraction using the paradigmatic model of a fast-moving laboratory within which a photon is emitted and posteriorly absorbed. In our model, however, the laboratory is composed of two independent parallel plates, each of which allowed to be sufficiently light so as to get kickbacks upon emission and absorption of light. We show that the lightness of the laboratory accentuates the time contraction. We also discuss how the photon frequency shifts upon reflection in a light moving mirror. Although often imperceptible, these effects will inevitably exist whenever realistic finite-mass bodies are involved. More fundamentally, they should necessarily permeate any eventual approach to the problem of relativistic quantum frames of reference.
