光速是不变的还是协变的？
Is the speed of light invariant or covariant?
摘要：
根据以太理论，光相对于绝对参考系和相对于任何其他参考系以恒定速度c传播，光速是协变的。根据狭义相对论，光速相对于任何参考系都是不变的。新的参考系理论对这个问题给出了不同的答案，它考虑了两种光速：物理速度和相对论速度。在考虑了两种主要理论的几个消极方面之后，阐述了新理论的几个基本原理。
英文摘要：
According to the theory of ether light propagates with constant speed c with respect to the absolute reference frame and with respect to any other reference frame the speed of light is covariant. According to the theory of special relativity the speed of light is invariant with respect to any reference frame. The new theory of reference frames gives a different answer to this question with the consideration of two speeds of light: the physical speed and the relativistic speed. After considering a few negative aspects of the two main theories a few fundamentals of the new theory are expounded.
